Diammonium phosphate Wikipedia

Diammonium phosphate (DAP; IUPAC name diammonium hydrogen phosphate; chemical formula (NH4)2HPO4) is one of a series of water-soluble ammonium phosphate salts that can be produced when ammonia reacts with phosphoric acid. Solid diammonium phosphate shows a dissociation pressure of ammonia as given by the following expression and equation: (NH 4) 2HPO 4(s) ⇌ NH 3(g) + (NH 4)H 2PO 4(s)
