Chemical compound

Ammonium phosphate is the inorganic compound with the formula (NH₄)_threePO₄. Information technology is the ammonium salt of orthophosphoric acid. A related "double salt", (NH₄)₃PO₄ ^.(NH_iv)_twoHPO_iv is likewise recognized but is impractical use. Both triammonium salts evolve ammonia. In contrast to the unstable nature of the triammonium salts, the diammonium phosphate (NH_iv)_twoHPO₄ and monoammonium table salt (NH₄)H_iiPO_four are stable materials that are usually used as fertilizers to provide plants with fixed nitrogen and phosphorus.^[3]

Preparation of triammonium phosphate [edit]

Triammonium phosphate can exist prepared in the laboratory past treating 85% phosphoric acid with xxx% ammonia solution:^{[ commendation needed ]}

H_threePO₄ + 3 NH₃ → (NH₄)₃PO_iv

(NH_iv)₃PO_four is a colorless, crystalline solid. The solid, which has the odor of ammonia, is readily soluble in water. The common salt converts to diammonium hydrogen phosphate (NH_four)₂HPO_four.
