Diammonium phosphate (DAP; IUPAC name diammonium 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 … See more DAP is used as a fertilizer. When applied as plant food, it temporarily increases the soil pH, but over a long term the treated ground becomes more acidic than before, upon nitrification of the ammonium. It is incompatible with See more The compound occurs in the nature as the exceedingly rare mineral phosphammite. The related dihydrogen compound occurs as the mineral biphosphammite.

Triammonium phosphate can be prepared in the laboratory by treating 85% phosphoric acid with 30% ammonia solution: 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. chisholm markbook
