Ammonium phosphate is the salt of ammonium and phosphate . It is a highly unstable compound with the formula (NH4)3PO4. Because of its instability, it is elusive and of no commercial value. A related “double salt”, (NH4)3PO4.(NH4)2HPO4 is also recognized but is too unstable for practical use. Both triammonium salts evolve ammonia. In contrast to the fragile nature of the triammonium salts, diammonium phosphate (NH4)2HPO4 is a valuable material, mainly as a fertilizer. Also of value is monoammonium salt (NH4)H2PO4 which is also valued as a fertilizer. These two salts provide plants with fixed nitrogen and phosphorus. [2]

Preparation of triammonium phosphate[ edit ]

Triammonium phosphate can be prepared in the laboratory by treating 85% phosphoric acid with 30% ammonia solution: [3]

H3PO4 + 3 NH3 → (NH4)3PO4

(NH4)3PO4 is a colorless, crystalline solid. The solid, which has the odor of ammonia, is readily soluble in water. The salt converts to diammonium hydrogen phosphate (NH4)2HPO4.

Preparation of diammonium hydrogen phosphate (DAP)[ edit ]

DAP is a simple salt and a complex fertilizer. [4] [5] It is also the source of nitrogen and phosphorus nutrients. [4] [5]

H3PO4 + 2 NH3 → (NH4)2HPO4

On heating, (NH4)2 HPO4 evolves ammonia, giving colorless crystals of the monoammonium salt.

(NH4)2 HPO4 is a colorless, odorless, crystalline solid, which insoluble in water. [4]
