Ammonium phosphate - Molar Mass = 149.12g/mol. The normal
ammonium phosphate, (NH4)3PO4, is obtained as a crystalline powder, on mixing concentrated solutions of ammonia and
phosphoric acid, or on the addition of excess of
ammonia to the acid phosphate (NH4)2HPO4. It is soluble in water, and the aqueous solution on boiling loses ammonia and the acid phosphate NH4H2PO4 is formed. Ammonium phosphate is used as an ingredient in some
fertilizers as a high source of elemental
nitrogen.
