A molecule with at least one hydrogen cation (H+) attached to an anion is referred to as an acid. The classification of acids is determined by whether or not the anion contains oxygen. If the anion does not contain oxygen, the acid is named with the prefix hydro- and the suffix -ic. For example, HCl dissolved in water is called hydrochloric acid. Likewise, HCN and H2S dissolved in water are called hydrocyanic and hydrosulfuric acids, respectively.

If the acid’s anion contains oxygen, the name is produced by appending the suffix -ic or -ous to the anion’s root name. If the anion’s name ends in -ate, -ic is used instead (or sometimes -ric).
H2SO4 is sulfuric acid because it contains the sulfate anion (SO42); H3PO4 is phosphoric acid because it contains the phosphate anion (PO43); and HC2H3O2 is acetic acid because it contains the acetate ion (C2H3O2). When naming acids with a -ite ending, the -ite is replaced with -ous.

H2SO3, which contains sulfite (SO32), is referred to as sulfurous acid, while HNO2, which contains nitrite (NO2), is referred to as nitrous acid. To demonstrate the principles for naming acids with oxygen-containing cations, the acids of the oxy anions of chlorine are utilized.

Compounds with complex ions

A coordination compound is composed of one or more complex structural units, each of which has a central atom bound directly to a surrounding set of groups called ligands. The nomenclature of coordination compounds is based on these structural relationships.
The details about organic compounds are given below:

Organic compounds

Organic compounds are molecules that contain carbon (C), and carbon atoms provide the structural foundation that allows organic compounds to be so diverse. Organic chemicals are essential to all species that can be classified as living on Earth (and most likely elsewhere in the universe).

Organic compounds include foodstuffs like lipids, proteins, and carbohydrates, as well as essential molecules like hemoglobin, chlorophyll, enzymes, hormones, and vitamins.

Clothing made of cotton, wool, silk, and synthetic fibres; common fuels, such as wood, coal, petroleum, and natural gas; components of protective coatings, such as varnishes, paints, lacquers, and enamels; antibiotics and synthetic drugs; natural and synthetic rubber; dyes; plastics; and pesticides are all organic compounds.

Structural formulas of some organic compounds

The structures of organic compounds can be depicted in condensed, expanded, and three-dimensional structural formulas.

Historical developments

At the end of the 18th century, when chemistry began to take on many of the hallmarks of a rational science, there was widespread agreement that experiment could reveal the principles that governed the chemistry of lifeless, inorganic materials.

The compounds that could be separated from live biological beings, on the other hand, appeared to have completely different compositions and properties than inorganic compounds.

Only a handful of the notions that allowed chemists to comprehend and manipulate the chemistry of inorganic molecules applied to organic compounds. The vast differences in chemical behavior between the two types of chemicals were assumed to be linked to their genesis.

Organic compounds could only be discovered in the tissues or remnants of living organisms, whereas inorganic substances could be collected from the Earth’s rocks, sediments, or oceans. As a result, it was assumed that organic molecules could only be generated by organisms working under the direction of a higher force exclusively in living things. This power was referred to as a vital force.

This vital force was thought to be a property inherent to all organic substances and incapable of being measured or extracted by chemical operations. Thus, most chemists of the time believed that it was impossible to produce organic substances entirely from inorganic ones.

By about the middle of the 19th century, however, several simple organic compounds had been produced by the reaction of purely inorganic materials, and the unique character of organic compounds was recognized as the consequence of an intricate molecular architecture rather than of an intangible vital force.

The first significant synthesis of an organic compound from inorganic materials was an accidental discovery of Friedrich Wöhler, a German chemist. Working in Berlin in 1828, Wöhler attempted to produce the inorganic compound ammonium cyanate by mixing two salts (silver cyanate and ammonium chloride).

To his amazement, he got a product with the same molecular formula as ammonium cyanate, but it turned out to be the well-known organic complex urea. Wöhler rightly reasoned from this unexpected result that atoms could arrange themselves into molecules in a variety of ways, and the attributes of the resulting molecules were highly reliant on the molecular architecture.

(An isomer of urea is now recognized to be the inorganic complex ammonium cyanate; both contain the same type and number of atoms but in different structural configurations.) Others were inspired by Wöhler’s discovery and succeeded in synthesizing simple organic compounds from inorganic ones, and by around 1860, it was widely accepted that a vital force was not required for organic compound synthesis and interconversion.

Despite the fact that a huge number of organic compounds have been synthesized since then, the structural complexity of particular compounds continues to pose significant challenges for the laboratory synthesis of complex molecules.

Modern spectroscopic techniques, on the other hand, enable chemists to deduce the exact architecture of complex organic molecules, and molecular attributes can be linked to carbon bonding patterns and structural features known as functional groups.


A molecule with at least one hydrogen cation (H+) linked to an anion is referred to as an acid. The classification of acids is determined by whether or not the anion contains oxygen. The acid is termed with the prefix hydro- and the suffix -ic if the anion does not include oxygen.

Hydrogen Sulfide’s Characteristics

Two hydrogen atoms and one sulfur atom make up hydrogen sulfide. Because hydrogen sulfide is denser than conventional air, it forms a blue flame when burned with oxygen. Water and sulfur dioxide are produced when hydrogen sulfide is burned. During a redox chemical reaction, hydrogen sulfide works as a reducing agent, a substance or element that loses an electron to another chemical.

Hydrogen sulfide and sulfur dioxide react with one another to generate water and sulfur when mixed with catalysts or at high temperatures. In industrial operations, this process is used to get rid of hydrogen sulfide.

Hydrogen sulfide is a weak acid that is water soluble, although not very so. When the solution is exposed to air, it oxidizes and produces sulfur.

Which isn’t water-soluble. Although hydrogen sulfide has a structure similar to water, sulfur has nowhere near the level of electronegativity that oxygen does, meaning that hydrogen sulfide is much less polar than water. Due to hydrogen sulfide’s less polar nature, the melting and boiling points for hydrogen sulfide are substantially lower than water’s boiling point.

Hydrogen sulfide boils at -60.7°C while water boils at 100°C.

Pure hydrogen sulfide, as well as solutions containing it, is colorless. When hydrogen sulfide combines with metal ions, it generates metal sulfides. These metal sulfides are usually black in color and insoluble in water. When metal sulfides are treated with a strong acid, hydrogen sulfide is produced.

Hydrogen sulfide molecules can carry electricity when under pressure greater than 90 gigapascals. When high-pressure hydrogen sulfide is cooled below a threshold temperature, it becomes superconducting. The critical temperature rises in tandem with the pressure. At 100 gigapascals, the critical temperature for hydrogen sulfide is anywhere between 23 K and 150 K.

The odor of hydrogen sulfide is so strong that it can be noticed at levels as low as 2 ppb. A concentration of 20 parts per billion (ppb) would equal 1 mL of gas uniformly distributed in a 100-seat college lecture hall.

The Production Of Hydrogen Sulfide is given below in details:

The Production Of Hydrogen Sulfide

Hydrogen sulfide is commonly created by isolating the molecules from sour gas, which is simply natural gas with high hydrogen sulfide concentrations. However, nitrogen sulfide can also be made by mixing molten sulfur with hydrogen at 450°C. During this process, hydrogen can be obtained from hydrocarbons.

As a waste product, sulfate-reducing bacteria create hydrogen sulfate. In low-oxygen settings, these bacteria generate energy by oxidizing hydrogen or organic molecules with different sulfates.

The liberation of hydrogen sulfide from nonmetal and metal sulfides such as phosphorous sulfide and aluminum sulfide, which can be done by exposing the sulfides to water, is another technique of creating hydrogen sulfide. If water heaters are employed, hydrogen sulfide gas can be produced more easily from sulfite because a stable heated habitat is provided for the sulfur bacteria that manufacture hydrogen sulfide.

Natural gas can contain up to 90% hydrogen sulfide, making it one of the most common ways to obtain hydrogen sulfide. Smaller amounts of hydrogen sulfide can also be found in crude petroleum.

Hydrolysis produces huge volumes of hydrogen sulfide, which is emitted by some natural hot springs and volcanoes. In well water, sulfate-reducing bacteria can produce hydrogen sulfide. The main industrial source of hydrogen sulfide is petroleum refineries.

Hydrogen sulfide can be produced by body cells via non-enzymatic or enzymatic mechanisms. Although enzymatic routes produce the majority of hydrogen sulfide produced in the body, nonenzymatic pathways use proteins such Rieseke proteins and ferredoxins to manufacture hydrogen sulfide. In modest amounts, the human body produces hydrogen sulfide by breaking down sulfur-containing proteins.

Biosynthesis in the body

In cells, hydrogen sulfide can be produced via an enzymatic or non-enzymatic process. In the body, H 2S acts as a gaseous signaling molecule that has been shown to inhibit Complex IV of the mitochondrial electron transport chain, lowering ATP production and metabolic activity.

The enzymes cystathionine-lyase (CSE), cystathionine-synthetase (CBS), and 3-mercaptopyruvate sulfurtransferase are known to produce H 2S. (3-MST). These enzymes have been found in a wide range of biological cells and tissues, and their activity has been linked to a variety of diseases. It’s getting clearer by the day that H

In both health and sickness, 2S is a key mediator of a variety of cell processes. The main proponents of HSE are CBS and CSE.

The trans-sulfuration route is followed by 2S biogenesis.

  • These enzymes are characterized by the transfer of a sulfur atom from methionine to serine to form a cysteine molecule. 3-MST also contributes to hydrogen sulfide production by way of the cysteine catabolic pathway.

  • Dietary amino acids, such as methionine and cysteine serve as the primary substrates for the transulfuration pathways and in the production of hydrogen sulfide. Hydrogen sulfide can also be synthesized by non-enzymatic pathway, which is derived from proteins such as ferredoxins and Rieske proteins.

  • H2S has been shown to be involved in physiological processes like vasodilatation in animals, increasing seed germination and stress responses in plants. Hydrogen sulfide signaling is also innately intertwined with physiological processes that are known to be moderated by reactive oxygen species (ROS) and reactive nitrogen species (RNS).

  • H2S has been shown to interact with NO resulting in several different cellular effects, as well as the formation of a new signal called nitrosothiol. Hydrogen sulfide is also known to increase the levels of glutathione which acts to reduce or disrupt ROS levels in cells.

  • The field of H2S biology has advanced from environmental toxicology to investigate the roles of endogenously produced H2S in physiological conditions and in various pathophysiological states.

  • According to a current classification, pathophysiological states with H2S overproduction (such as cancer and Down syndrome) and pathophysiological states with H2S deficit (e.g. vascular disease) can be identified.

  • Although the understanding of H2S biology has significantly advanced over the last decade, many questions remain, for instance related to the quantification of endogenous H2S levels.

Uses For Hydrogen Sulfide

The most common use of hydrogen sulfide is as a catalyst for obtaining elemental sulfur. Hydrogen sulfide is used to make a variety of organosulfur compounds, including ethanethiol and methanethiol, among others.

Alkali Hydrosulfides, such as sodium Hydrosulfide and sodium sulfide, are formed when hydrogen sulfide reacts with alkali metal bases. Paper marking is one of the most common applications for sodium sulfide and other alkali hydrosulfides.

Metal ions and hydrogen sulfide are combined to form a variety of metal sulfides. This metal sulfide conversion can be used to clear contaminated water or gas. Hydrogen sulfide is commonly used to treat mineral powders and to help metal ores separate during the flotation process.

Hydrogen sulfide gas is capable of staving off mitochondrial damage when applied to cells in small amounts. Hydrogen sulfide is also frequently used to separate out heavy water, or deuterium oxide, from regular water.


Hydrogen sulfide is slightly denser than air. A mixture of H2S and air can be explosive. Hydrogen sulfide burns in oxygen with a blue flame to form sulfur dioxide (SO2) and water. In general, hydrogen sulfide acts as a reducing agent, especially in the presence of base, which forms SH−.

Hydrogen Sulfide Dangers

Hydrogen sulfide is flammable, explosive at times, caustic, and poisonous.

Because hydrogen sulfide is a broad-spectrum toxin, it can harm a variety of physiological systems and organs. However, hydrogen sulfide has the greatest impact on the nervous system. In terms of harm, hydrogen sulfide poisoning is analogous to carbon monoxide poisoning, and it also impairs cellular respiration.

Because the body creates hydrogen sulfide naturally, the gut has many enzymes that help to detoxify it. Around 50 ppm, hydrogen sulfide is expected to begin causing significant damage to the body, and the Occupational Safety Hazard Association recommends a maximum value of 20 ppm. Because hydrogen sulfide is heavier than air, it tends to congregate along the floor at dangerous amounts in poorly ventilated spaces.

Low levels of hydrogen sulfide can induce symptoms such as shortness of breath, nausea, and vomiting. Cough, sore throat, and eye irritation are all symptoms of pulmonary edema. Within a few days to weeks, these symptoms normally go away.

However, even low levels of hydrogen sulfide exposure can cause headaches, memory loss, dizziness, and exhaustion over time. At doses of > 300 ppm, severe pulmonary edema, cessation of breathing, and death are possible.

Hydrogen Sulfide’s Effects on the Environment

The sulfur cycle refers to the abiotic and biotic mechanisms that cycle sulfur through the earth. Hydrogen sulfide is one of the key constituent molecules in the sulfur cycle.The sulfur cycle is divided into four stages. The first process is converting organic sulfur into inorganic sulfur, such as hydrogen sulfide.

Low levels of hydrogen sulfide can induce symptoms such as shortness of breath, nausea, and vomiting. The second phase involves the oxidization of those inorganic forms of sulfur, with sulfide, elemental sulfur, and sulfate being oxidized by purple and green sulfur bacteria.

After this, there is a reduction of sulfate into sulfide, specifically dissimilative sulfur reduction. Finally, sulfide is incorporated into a variety of different organic compounds which include sulfide derivatives that contain metal.

Bacteria that decrease sulfur or sulfate will utilise the sulfates present in the environment to oxidize and destroy organic matter when it decays in low oxygen environments. As a consequence of this process, hydrogen sulfide is produced. By interacting with metal ions, hydrogen sulfide transforms into metal sulfides.

Other bacteria, on the other hand, remove hydrogen sulfide from sulfur-containing amino acids. During photosynthesis, green sulfur bacteria and purple sulfur bacteria use hydrogen sulfide as an electron donor to generate elemental sulfur.

While most creatures are harmed by hydrogen sulfide exposure, a few extremophile species may survive and thrive in sulfide-rich environments. A variety of microbes and fish, for example, reside near hydrogen sulfide-emitting hydrothermal vents.

Similarly, there are freshwater springs that have high hydrogen sulfide levels, and these springs are home to a handful of fish species and invertebrates.

What is the occurrence of hydrosulfrous acid:


Volcanoes and some underground aquifers (just as chilly springs) transmit some H**2S, where it most likely emerges by means of the hydrolysis of sulfide minerals, for example MS + H2O → MO + H2S.[citation needed]

Hydrogen sulfide can be available normally in well water, regularly because of the activity of sulfate-diminishing microbes. Hydrogen sulfide is made by the human body in little portions through bacterial breakdown of proteins containing sulfur in the digestive system, along these lines it adds to the trademark scent of tooting. It is additionally delivered in the mouth (halitosis).

A piece of worldwide H2S outflows are because of human action. By a wide margin the biggest modern wellspring of H2S is petrol treatment facilities: The hydrodesulfurization interaction frees sulfur from petrol by the activity of hydrogen.

The subsequent H2S is changed over to essential sulfur by fractional ignition through the Claus cycle, which is a significant wellspring of basic sulfur. Other anthropogenic wellsprings of hydrogen sulfide incorporate coke stoves, paper plants (utilizing the Kraft interaction), tanneries and sewerage.

H2S emerges from for all intents and purposes anyplace where basic sulfur interacts with natural material, particularly at high temperatures. Contingent upon ecological conditions, it is answerable for decay of material through the activity of some sulfur oxidizing microorganisms. It is called biogenic sulfide consumption.

In 2011 it was accounted for that expanded groupings of H2S were seen in the Bakken development rough, conceivably because of oil field rehearses, and introduced difficulties, for example, “wellbeing and ecological dangers, erosion of wellbore, added cost as to materials dealing with and pipeline gear, and extra refinement prerequisites”.

Other than living close to gas and oil penetrating tasks, standard residents can be presented to hydrogen sulfide by being close to squander water treatment offices, landfills and homesteads with compost stockpiling. Openness happens through breathing tainted air or drinking sullied water.

In civil waste landfill destinations, the internment of natural material quickly prompts the creation of anaerobic assimilation inside the waste mass and, with the sticky climate and moderately high temperature that goes with biodegradation, biogas is delivered when the air inside the waste mass has been decreased.

Assuming there is a wellspring of sulfate bearing material, like plasterboard or regular gypsum (calcium sulfate dihydrate), under anaerobic conditions sulfate lessening microscopic organisms changes this over to hydrogen sulfide.

These microscopic organisms can’t get by in air however the damp, warm, anaerobic states of covered waste that contains a high wellspring of carbon – in idle landfills, paper and paste utilized in the manufacture of items, for example, plasterboard can give a rich wellspring of carbon – is a superb climate for the development of hydrogen sulfide.

In modern anaerobic assimilation processes, for example, squander water treatment or the absorption of natural waste from agribusiness, hydrogen sulfide can be framed from the decrease of sulfate and the corruption of amino acids and proteins inside natural mixtures. Sulfates are somewhat non-inhibitory to methane shaping microbes yet can be decreased to H2S by sulfate lessening microscopic organisms, of which there are a few genera.


Hydrogen sulfide (combustible reach: 4.3 46%) is an extremely harmful and combustible gas. It will in general gather at the lower part of ineffectively ventilated regions since it is heavier than air.

Despite the fact that it smells like spoiled eggs from the get go, it rapidly dulls the feeling of smell, causing a short episode of anosmia, so casualties might know nothing about its reality until it’s past the point of no return. A hydrogen sulfide security information sheet (SDS) ought to be analyzed for safe taking care of practices.


The most famous strategy for getting hydrogen sulfide is to isolate it from harsh gas, which is flammable gas with a high convergence of H 2S. It can likewise be made by blending hydrogen in with liquid essential sulfur at 450 degrees Celsius. Hydrocarbons can be utilized as a hydrogen source in this strategy.

:large_blue_diamond: Reactivity

When sulfuric acid comes into contact with a substance that has been exposed to it for a long period, it can cause charring. Sulfuric acid is very reactive and can dissolve almost any metal.

Heating occurs when sulfuric acid combines with alcohol and water. As water dilutes the metals, it reacts, and the resulting hydrogen gas is highly explosive. Long-term or short-term inhalation exposure to low quantities or high concentrations might cause harmful health effects.

Sulfuric acid is not explosive, but it is a powerful oxidant that facilitates the combustion of other compounds but does not burn itself. During a fire, toxic gases are released into the air. Decomposition products that pose a health risk include sulfide dioxide, sulfuric acid fumes, and sulfuric acid gases.


Aqueous sulfuric acid solutions ionize entirely to create hydronium ions (H3O+) and hydrogen sulfate ions (HSo4). Sulfuric acid is a very powerful acid. H2SO4 dissociates to produce hydronium ions (HNO3) and sulfate ions (SO42) in diluted solutions.

To describe solutions of sulfur trioxide in 100 percent sulfuric acid, the word “oleum” is used; these solutions typically contain 20 to 65 percent sulfur trioxide, and they are utilized to prepare organic compounds.

Additionally, concentrated sulfuric acid is an effective dehydrator, interacting forcefully with water to burn various organic materials such as wood, paper, and sugar, leaving a carbonaceous residue. This property makes it an excellent oxidizing agent.

Summary :blue_book:

Sulfuric acid is a colorless, odorless, and viscous liquid. Water can be dissolved by heating it. Metals and tissue are corrosive to the substance. Most organic stuff can be charred in contact with this substance without setting something on fire. The density is 15 pounds per gallon.

H2SO4 sulfuric acid is one of many sulfuric acid-related chemicals known as sulfates. Sulfate ions, SO42, and positively charged ions such as sodium, magnesium, or ammonium make up one of these derivatives.


The other group is made of esters in which sulfuric acid’s hydrogen atoms are substituted by carbon-containing groups such as methyl (CH3) or ethyl (CH2) (C2H5).

:diamond_shape_with_a_dot_inside: Carbonate

Chemical molecules are produced from either carbon dioxide or carbonic acid, known as carbonate (q.v.). Metal ions such as sodium or calcium can also be found in inorganic carbonates because of their association with the CO2/3- ion in CO2/3-H2CO3.

Many minerals, including limestones and dolomites, contain inorganic carbonates, also found in the hard sections of many marine creatures (see “carbonate mineral”). When the hydrogen atoms in carbonic acid are swapped out for carbon-containing linking groups like ethyl, C2H5, organic carbonates are esters.

:diamond_shape_with_a_dot_inside: Phenol

There are many types of Phenols, and they all have one thing in common: They are all aromatic chemicals. Additionally, monohydroxybenzene (C6H5OH), commonly known as benzenol or carbolic acid, is the generic name for the complete phenol family.

Like alcohols, phenols have a stronger hydrogen bond, making them more stable. As a result, they are more easily dissolved in water and have higher boiling temperatures than alcohol. There are two forms of phenols at room temperature: colorless liquids or solid white powders. They can be exceedingly poisonous and corrosive.


A wide variety of household items and industrial processes rely on phenolic compounds. Phenol, for example, is used as a disinfectant in home cleaners and mouthwash at low doses. One theory holds that phenol was the first antiseptic used in surgery. He utilized phenol as an antiseptic in his operating room in 1865 by British physician Joseph Lister.

In Lister’s ward, mortality from surgical amputations dropped from 45 to 15 percent when phenol was used in this manner. Toxic but non-painful burns can be caused by concentrated phenol solutions, which is why it is best to avoid contact with it. n-hexylresorcinol.

Plastics, explosives like picric acid, and medicines like aspirin are all made from phenol. Silver bromide crystals exposed to light are reduced to black metallic silver using the ubiquitous phenol hydroquinone component of the photographic developer.

Other substituted phenols are utilized in the dye industry to create brightly colored azo dyes. Preservatives like creosote use phenolic compounds, particularly cresols, as components. Toxicologically, BHT is far less harmful than other antioxidants, and it’s a frequent ingredient in many meals.

:diamond_shape_with_a_dot_inside: Inorganic chemistry for industrial use.

Sulfuric acid (H2SO4) is an inorganic chemical that is very corrosive, ethereal, colorless to slightly yellow, viscous, and soluble in water at all concentrations. Sulfuric acid is the original name for the oil of vitriol.

As sulfuric acid is utilized in a wide variety of processes worldwide, the chemical’s production is often related to a country’s level of development because of the wide range of applications. One of the most important raw materials in many industrial and manufacturing processes is sulfuric acid (H2SO4).

There are several uses for sulfuric acid, including copper leaching, inorganic pigments, the refinement of petroleum, the making of paper and industrial organic chemicals, and the phosphate fertilizer industry.

Natural phenols include:

  • List items amino acid tyrosine.

  • List item The adrenal medulla produces epinephrine (adrenaline).

  • List item Serotonin, which is secreted in large amounts by the brain.

  • List item Urushiol, an irritant made by the poison ivy plant to keep animals from eating its leaves.

From the essential oils of plants, many of the more complex phenolic compounds utilized to flavor and aromatize foods can be obtained. From these sources, vanilla flavoring vanillin and methyl salicylate may be extracted, with distinct minty flavors and aroma.

In addition to thymol and eugenol, which may be found in thyme and cloves, other phenols can be separated from plants.

:diamond_shape_with_a_dot_inside: Phenol nomenclature

Many phenolic compounds were discovered and used before chemists were able to identify their chemical structure. This means that names like vanillin, salicylic acid, pyrocatechol and resorcinol, cresol, and hydroquinone are often used for phenolic compounds (eugenol vanillin and salicylic acid).

To be more precise, systematic names better describe the compound’s structure. In this case, the chemical can be called a “substituted” phenol since the carbon-atom one carbon has the hydroxyl group attached to it. Systematic thymol’s name is 5-methyl-2-isopropyl phenol.

It is possible to name phenols with only one additional substituent utilizing the ortho (1,2), meta (1,3), and para (1,4) systems. The hydroxyl group can be used as a hydroxy substituent in naming compounds with other functional groups. Vanillin, for instance, has the scientific name 4-hydroxy-3-methoxy benzaldehyde.
