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 .
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]
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
The phosphate ion has a molar mass of 94.97 g/mol, and consists of a central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. It is the conjugate base of the hydrogen phosphate ion H(PO 4) 2−, which in turn is the conjugate base of the dihydrogen phosphate ion H 2 (PO 4) −
The general formula of a phosphoric acid is H n−2x+2 P n O 3n−x+1, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure; that is, the minimum number of bonds that would have to be broken to eliminate all cycles.
Ammonium phosphate is the inorganic compound with the formula (NH 4) 3 PO 4. It is the ammonium salt of orthophosphoric acid. A related "double salt", (NH 4) 3 PO 4. (NH 4) 2 HPO 4 is also recognized but is impractical to use. Both triammonium salts evolve ammonia.
