Molecular formula: NH4H2PO4
Molecular weight: 115.03
Properties: white crystal. The relative density is 1.803 and melting point is 190 centigrade. It is easily soluble in water and slightly soluble in alcohol, insoluble in acetone. It is stability in the air, and decompounds only a little at 100 centigrade. It loses ammonia and water, and becomes ammonium metaphosphate and phosphoric acid exceeding 190 centigrade.
