Phosphoric Acid

Phosphoric acid (PA), also known as orthophosphoric acid or phosphoric(V) acid, is a weak mineral acid with the chemical formula H₃PO₄. Phosphoric acid is typically a colorless syrup of 75-85% concentration in water.

Phosphoric acid is a weak triprotic acid. It is a weak acid because it only partially ionizes in solution. Since PA requires three steps to reach complete ionization, it is termed triprotic.

Manufacturers apply phosphoric acid in some reactions involving other materials to produce certain products. Phosphoric acid, when combined with a base (neutralization reaction), will react violently and produce water, salt, and heat (heat of neutralization).

Phosphoric acid is an essential plant nutrient. The agriculture industry uses fertilizers with phosphoric acid to rectify phosphorus deficiencies in soils. Agriculture uses more than 80% of the phosphoric acid on the market to make fertilizer.

In addition to fertilizer manufacturers, companies use PA for metal surface treatment in the metallurgical industry and as an additive in the food industry.
