Because sodium hydroxide is highly alkaline, it is corrosive, making it an excellent wastewater treatment agent for removing grease and grime.

Does caustic raise pH?

Sodium Hydroxide (Caustic Soda) Sodium hydroxide is used to raise the pH of water in several areas. The chemical leaves no color residue, it is a very durable product and is available in a concentration of 250%.

What pH has the highest concentration of hydroxide ions?

The pH of a solution is a measure of the concentration of hydrogen ions in a solution. A solution with a lot of hydrogen ions is acidic and has a low pH. A solution with a large amount of hydroxide ions is basic and has a high pH. The pH scale runs from 14 to 14, with pH 7 being neutral.

Is sodium hydroxide strong or weak?

Sodium hydroxide (NaOH) is a strong base because it completely dissociates in water to form hydroxide ions. Ammonia (NH 3), on the other hand, is a weak base because it absorbs protons from water to produce fewer hydroxide ions in solution.
