Di Ammonium Phosphate 7783-28-0

Di Ammonium hydrogen phosphate; chemical formula (NH4)2(HPO4) 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:
(NH4)2HPO4(s) NH3(g) + (NH4) H2PO4(s)At 100 A C, the dissociation pressure of diammonium phosphate is approximately 5 mmHg.
