H2SO4, or sulphuric acid, has an approximate molar mass of 98 Daltons and an average molar mass of 98 Daltons . It has two atoms of hydrogen and one atom of sulfur per molecule, and each hydrogen atom binds to an oxygen atom on the other molecule.



  1. A very strong acid, H2SO4 dissociates in water to form an H+ and an SO42−. The ionic formula of sulfuric acid is, therefore, HSO4−, although it is rarely written as such.

  2. Because concentrated sulfuric acid tends to revert into H2SO4 when it reacts with metal or nonmetal oxides, it can be used to clean metal objects.

  3. It dissolves carbonates, silicates, phosphates, and sulfides. Hydrochloric acid (HCl) is a better choice for cleaning nonmetallic substances because it is more selective in what it dissolves.

  4. Sulfuric acid will attack most metals and dissolve them into hydrogen gas and a metal ion.

  5. It is common to describe how strongly or weakly an acid reacts by its pKa. The lower its pKa, which stands for acid dissociation constant, indicates a stronger acid.

  6. Sulfuric acid has a value of −6.5, which makes it much stronger than hydrochloric acid’s pKa of −9.21, for example. Stronger acids will react more quickly with metals and other substances to form ionic bonds.

  7. Sulfuric acid is a component of car batteries, which are made up of many metallic substances. It can also be used to make fertilizers that contain potassium and phosphorus ions by reacting with an appropriate base.

  8. One example is muriate of potash, which is KCl mixed with H2SO4. This compound dissociates in water to release K+ and Cl− ions. When dealing with concentrated sulfuric acid solutions it is important to take steps for your safety.

H2So4 Reaction

  • I would like to discuss my experiment on how H2So4 will react with KMnO4. I found out that when you add equal amounts of both together it creates a black solid substance along with a foamy watery layer on top.

  • It reacted similarly to sulfuric acid and potassium permanganate(KMnO4). I think my experiment went well but there are a few things that can be improved upon 1) Be careful while pouring so you don’t spill or splash any.

  • I also found out that MnO2(which is solid) will dissolve into water. What I didn’t find out was what would happen if you put them both together and let them sit for some time. It may have turned into a solution which would be HSO4- or another precipitate.

Overall, I think my experiment went well, but there is room for improvement when conducting similar experiments in the future.

  • I think that my experiment was a success because of all of my observations. If you are careful when pouring in your solutions and can avoid spilling anything, then your experiment will be more successful than mine.

  • It is important to get everything out at once and not let things sit around for a long time. If you do it right and pour slowly, it shouldn’t even create a mess.

  • I think that H2SO4 is fairly safe to work with. It burns/causes irritation if it gets in your eyes, and can cause a skin rash if you don’t wash your hands right after handling it or by being exposed to high concentrations of sulfuric acid.

  • If anything spills on you make sure you wash it off quickly because H2SO4 will start eating through most things almost instantly.

H2So4 Uses

It is a white crystalline solid. It dissolves to give water solutions of sulfuric acid (the acid) and its anion, which exist in equilibrium and is used for preparing pure water: H2SO4(aq) + H2O → H3O+(aq) + SO42-(aq).

Some of its uses include chemical synthesis, oil refining, pulp bleaching, mineral dressing processes, etc.

  1. The term sulfuric acid can refer to several different species of acid, including a hydrated sulfate, bisulfate, and polysulfate, each with a different chemical formula. The sulfate and bisulfate anions are both salts of sulfuric acid.

  2. Sulfuric acid is usually produced by oxidation of some sulfur-containing material; typical sources include hydrogen sulfide gas (typically derived from natural gas) and purified sulfur dioxide.

  3. The elemental form is used in many applications, such as battery electrolyte, inorganic fiber manufacturing, mineral extraction, and chemical textile processing.

  4. The anion salts are used in agricultural fertilizer (acidification) and metal finishing. Sulfuric acid also finds specialized uses in many processes that generate sulfur dioxide or its corrosive oxidation products, especially concentrated solutions of oleum (fuming sulfuric acid).

  5. It can also be used in building exteriors and gypsum plaster. In organic synthesis, it is commonly used to remove protecting groups from functional groups, usually alcohols, or acyl chlorides.

H2So4 + Naoh

  1. H20, Sulfuric acid, Sulfurous acid, Sulphuric acid. Water (h2o) can be decomposed into oxygen (0) and hydrogen gas (h3o).

  2. This method is most commonly used in submarines and space shuttles where gas vented during a hyperbolic maneuver needs to be vented quickly.

  3. The water is not made directly by electrolysis but rather by reacting solid sulfur with concentrated hydrochloric acid.

  4. Because it tends to hydrolyze, solutions of HCl are usually stored in plastic bottles or cylinders, although older glass containers have been used.

  5. As plastic containers age, they can become brittle and crack if exposed to ultraviolet light. This process can lead to leaks which can be difficult to detect because the gas produced by hydrolysis is heavier than air.

  6. Solutions of sulfuric acid with concentrations of greater than 98% are sometimes called oils because they are less dense than water. Such solutions have a density between 1.21 and 1.31 g/cm3.


Concentrated sulfuric acid is one of two chemicals banned from transport aboard passenger aircraft by all major civil airlines. Concentrated sulfuric acid can pose a hazard to personnel in case of an accident. H2SO4 is shipped as a class 9 dangerous goods in non-bulk packages (packages with 50 kg net mass or more) and must be labeled with compatible PG II labels.

H2So4 Ph

The P stands for Phosphorus. If there is no phosphorus in a chemical, then it is considered to be non-toxic and safe to touch. H2So4 has 4 electrons.

Which makes it stable enough that it doesn’t react easily with other chemicals, meaning you can drop some on your counter or leave a glass of it open for months and nothing will happen.

If you spill pure H2So4 on your skin it will simply wash off. This is why so many companies use diluted sulphuric acid to strip paint off their products before they ship them.

  1. The acid is non-toxic and effective at stripping paint, but doesn’t damage the metal underneath and can easily be washed away.

  2. The P in H2So4 stands for Phosphorus. If a chemical has phosphorous, it is very toxic and it can also spontaneously combust (burning without being exposed to air). The H2O in H2SO4 is water, making it basic.

  3. This means that you should use eye protection when working with it because both sulphuric acid and water are extremely corrosive to the eyes.

  4. Another interesting thing about H2SO4 is that it can absorb 9 times its volume in water, which means you can make your dry ice from a small amount of sulphuric acid and dry ice.

  5. If you are working with H2SO4 and don’t have gloves, you will want to wear long sleeves so that it doesn’t touch your skin at all. It will burn right through clothing very quickly.

  6. When you are working with a concentrated solution of H2SO4, you need to be careful because it is very corrosive. If any is spilled on you, immediately wash it off with soap and water, and then rinse your eyes out.

  7. If it touches your skin at all, wash that area immediately as well. Be extremely careful when working with any solutions stronger than 50% acidity because even if you manage to avoid getting anything in your eyes, they will sting badly.

Why Is H2So4 A Strong Acid

  1. The molar mass of H2SO4 is 98.1. It’s important to know that an element or ion’s molar mass doesn’t change when it loses or gains electrons.

  2. Based on its molar mass, H2SO4 is a strong acid. This means that it dissociates or breaks apart completely in water to form ions.

  3. It’s also known as a diprotic acid because it has two protons and thus can donate up to two electrons when it dissociates. H2SO4 exists only as a proton donor.

  4. For a diprotic acid to donate two protons, it must be charged in water and dissociate completely. For example, HCl is a strong acid because it has only one proton and can donate only one electron.

Therefore, HCl only partially dissociates in water to form hydrochloric acid ions. Water’s ability to accept H+ ions is called its pH value.

  1. The common range of pH values is from 0 to 14. The lower a substance’s pH value, the more acidic it is. A substance with a higher pH value has greater basicity and is called a base.

  2. Acids have low pH values while bases have high values. Pure water can be thought of as neutral because it has a neutral pH value of 7, which means it’s neither an acid nor a base.

  3. Hydrogen peroxide can be considered a strong acid because it is diprotic, like H2SO4. While H2SO4 has a molar mass of 98.1 and dissociates completely to form sulfate ions, hydrogen peroxide has a molar mass of 34.0 and only partially dissociates in water to form peroxide ions.

  4. Although stronger acids exist, hydrogen peroxide is one of them due to its low molar mass and high level of dissociation in water.

H2So4 Acid Or Base

It is a weak acid. This means that it partially ionizes in water, forming H3O+, which then reacts with OH- to form H2O and HSO4- ions.

In general, acids form hydronium ions when dissolved in water. A strong acid will dissociate completely, but a weak acid will only partially dissociate.

  1. The pH scale was created to rate how acidic or basic a solution is. A solution with a pH of less than 7 is considered acidic, and a solution with a pH of greater than 7 is considered basic. Acids have low pH values, and bases have high pH values.

  2. The pH scale ranges from 0 to 14. Solutions with a pH of less than 7 are acidic, and solutions with a pH greater than 7 are basic. Solutions that are neither acidic nor basic have a neutral pH of 7. Pure water has a neutral pH of 7.

  3. Strong acids completely dissociate in water, so their solutions have a pH of less than 7. In contrast, weak acids only partially dissociate and have a pH greater than 7.

  4. The pH scale is logarithmic, so a solution with a pH of 3 is 10 times more acidic than a solution with a pH of 4. Similarly, a solution with a pH of 5 is 100 times more acidic than one with a pH of 6.

M H2So4

Since H2SO4 is a tricrotic acid, it will dissociate in water according to H2SO4 + H2O —> H3O+ + SO42− The 1 indicates that H3O+ and SO42− dissociate completely. Thus, 2 ■■■■■ of solution will contain 3 ■■■■■ of hydrogen ions and 1 mole of sulfate ions.

The molar mass of H2SO4 is 98.076 g/mol, which tells us that 1 mole of sulfuric acid will contain 98.076 grams of H2SO4 molecules in solution.

Now that we know how many ■■■■■ and grams of H2SO4 are in 1 liter of solution, we can find its density as a function of volume.

  1. Taking 98.076 grams per mole, and multiplying it by 1 liter of solution gives us 98.076 g of H2SO4 in 1 liter of solution. This means that if we were to take any volume of sulfuric acid (up to 1 liter), it would have a mass equal to its volume.

  2. We can rewrite our previous equation as V = M/d, where V is volume, M is molar mass, and d is density.

  3. Density (d) is given by d = M/V, so rearranging our equation gives us: V = M/(d·d), where d·d represents a molecular mass of 2 × 98.076 g/mol or 196.148 g/mol.

  4. This means that to find any volume of solution in liters, we multiply that number by 196.148 g/mol to get grams per liter.

Sulphuric Acid

Sulfuric acid is one of several inorganic acids produced on a large scale in the industry. It has important applications in many fields, such as oil refining and chemical synthesis.

In domestic settings, it is used as a corrosive, a cleaning agent, and a descaling agent. It is also found naturally in volcanic activity, hot springs, and other places where bacteria interact with oxygen-rich water.

When heated to very high temperatures (around 170°C), sulfur trioxide converts to sulfur dioxide and water vapor.

Sulfuric acid is a strong mineral acid with many uses. In its pure form, it is colorless and odorless. It dissolves readily in water to form sulfuric acid solution (H2SO4).

Sulfuric acid was discovered in 1680 by an Italian chemist named Francesco Luc redi. He noticed that heating sulfur gave off a vapor that turned into liquid when exposed to air.

The substance, which is now known as sulfur trioxide, can be produced when copper and sulfur are mixed. This procedure is called the ‘contact process’. Sulfuric acid was first used in 1752, as a treatment for the indigo dye to make it soluble in water.

A British chemist named John Roebuck improved on it by suggesting that sulfuric acid should be boiled to reduce its density. Now, sulfuric acid is produced on a large scale using an industrial process called the wet sulfuric acid process.


HCo3 is a chemical compound that can be found in antacids. It’s a milder form of H2CO3 and functions in antacids to balance out acid levels that can cause indigestion.

People with symptoms of acid reflux will benefit from taking antacids containing HCo3, as they help reduce symptoms such as sore throats and coughing fits caused by excess acidity.

When you suffer from acid reflux, it’s possible that a disruption in your body’s pH balance is to blame.

Antacids help restore that balance by limiting and raising pH levels as needed. HCo3 is part of antacid solutions to keep acid levels at bay so you can get back to living your life.

One of the most prevalent forms of acid reflux is caused by lifestyle choices. The pH balance that regulates your stomach’s ability to digest food gets thrown off-kilter when you consume too much coffee, alcohol, and/or soda pop.

These are all common offenders for triggering heartburn in people who don’t already suffer from it. The most effective way to control these triggers is to reduce or eliminate them from your diet.

Antacids can be used to combat symptoms of acid reflux. They work by neutralizing excess acid in your stomach and keeping it from moving up into your esophagus. You’ll usually find that using antacids comes with some side effects, such as bloating and constipation.

If you experience any persistent side effects or don’t see a decrease in your symptoms after one month of treatment, you should discuss switching antacid brands with your doctor.


Molar mass is found when you divide 1 by several molecules, gram per molecule, and Avogadro’s constant. Molar mass = g/mol x ■■■■■/mol x 6.022x10^23. One mole of sulfuric acid has a mass of 98 grams. Sulfuric acid is made up of two elements: Sulfur (S) and Oxygen (O). The atomic weight for sulfur is 32.06 grams per mole, while oxygen has an atomic weight of 15.99 grams per mole; therefore a single molecule consists of 2 atoms: one atom of oxygen and one atom of sulfur.
