Neutralization Chemicals - Sulfuric Acid


Sulfuric Acid H2SO4

Sulfuric Acid H2SO4: The most widely used and produced chemical in the world. Available in concentrations ranging from 0% to 98% (with 93% being the most popular) sulfuric is also the least expensive acid to use. Sulfuric acid is used almost universally for neutralization reactions. It is easier and safer to use than HCl or HNO3 and is more potent than all of the other acids except for phosphoric. Although adverse reactions are always a possibility, they are rare. If calcium is present then calcium sulfate (CaSO4), also known as gypsum, will precipitate. Unless calcium is abundantly present this is not an issue. Sulfuric acid is typically used in concentrations ranging from 25% to 93%.

Generally this is a safe and inexpensive acid to use for the neutralization of alkaline materials.
