Diammonium phosphate (DAP) (chemical formula (NH₄)₂HPO₄, IUPAC name diammonium hydrogen phosphate) 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: (NH₄)₂HPO₄(s)<=>NH₃(g)+NH₄H₂PO₄(s) At 100 °C, the dissociation pressure of diammonium phosphate is approximately 5 mmHg.
