Triammonium phosphate can be prepared in the laboratory by treating 85% phosphoric acid with 30% ammonia solution: [citation needed] H 3 PO 4 + 3 NH 3 → (NH 4) 3 PO 4 (NH 4) 3 PO 4 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 (NH 4 ...
Ammonium dihydrogen phosphate (ADP), also known as monoammonium phosphate (MAP) [5] is a chemical compound with the chemical formula (NH 4)(H 2 PO 4). ADP is a major ingredient of agricultural fertilizers [6] and dry chemical fire extinguishers. It also has significant uses in optics [7] and electronics. [8]
Ammonium phosphate refers to three different chemical compounds, all of which are formed by the reaction of ammonia with phosphoric acid and have the general formula [NH 4] x [H 3−x PO 4], where 1 ≤ x ≤ 3: Ammonium dihydrogenphosphate, [NH 4][H 2 PO 4] Diammonium phosphate, [NH 4] 2 [HPO 4] Ammonium phosphate, [NH 4] 3 [PO 4
It uses a specially fluidized and siliconized monoammonium phosphate powder. [1] ABC dry chemical is usually a mix of monoammonium phosphate and ammonium sulfate, the former being the active component. The mix between the two agents is usually 40–60%, 60–40%, or 90–10% depending on local standards worldwide.

Diammonium phosphate (DAP; IUPAC name diammonium hydrogen phosphate; chemical formula (NH 4) 2 (HPO 4)) 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 of ammonia as given by the following expression and equation: [2]
Monopotassium phosphate (MKP) (also, potassium dihydrogen phosphate, KDP, or monobasic potassium phosphate) is the inorganic compound with the formula KH 2 PO 4. Together with dipotassium phosphate (K 2 HPO 4. (H 2 O) x) it is often used as a fertilizer, food additive, and buffering agent.
The term phosphate is also used in organic chemistry for the functional groups that result when one or more of the hydrogens are replaced by bonds to other groups. These acids, together with their salts and esters , include some of the best-known compounds of phosphorus, of high importance in biochemistry , mineralogy , agriculture , pharmacy ...
