Diammonium phosphate - Wikipedia
Diammonium phosphate (DAP; IUPAC name diammonium hydrogen phosphate; chemical formula (NH 4) 2 (HPO 4)) 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: [2]
