Other applications

One of the most important applications of phosphoric acid is the production of chemical fertilizers for agriculture. They are produced with the use of calcium phosphate salts, namely calcium hydrogen phosphate – CaHPO4 – and calcium superphosphate – Ca (H2PO4) 2. Other salts important in industrial and laboratory applications are sodium dihydrogen phosphate used as a solution acidity regulator, sodium hydrogen phosphate used to precipitate metal ions from solutions, and sodium phosphate found in soaps and detergents.

Phosphoric acid is used in dentistry and orthodontics as an etching solution to clean the surfaces of the teeth before placing dental fillings on them. It is added to pharmaceutical products as a pH buffer.
