A phosphate (PO43−) as an inorganic chemical is a salt of phosphoric acid. Inorganic chemistry, a phosphate, or organophosphate, is an ester of phosphoric acid. Organic phosphates are important in biochemistry and biogeochemistry or ecology. Inorganic phosphates are mined to obtain phosphorus for use in agriculture and industry

Phosphate is useful in animal cells as a buffering agent. Phosphate salts that are commonly used for preparing buffer solutions at cell pHs include Na2HPO4, NaH2PO4, and the corresponding potassium salts.

Di Ammonium phosphate (DAP) (chemical formula (NH4)2HPO4, IUPAC name Di Ammonium hydrogen phosphate) is one of a series of water-soluble ammonium phosphate salts that can be produced when ammonia reacts with phosphoric acid. Solid Di ammonium phosphate shows a dissociation pressure of ammonia as given by the following expression and equation
