Phosphoric acid (orthophosphoric acid or monophosphoric acid) is mainly used as an acidifying agent. Phosphoric acid is also the starting material for the production of various phosphates. It is a clear and odourless liquid.

Salts of phosphoric acid are called phosphates. Diphosphates (E 450), triphosphates (E 451) and polyphosphates (E 452) are also used as food additives.
