Description

Monoammonium phosphate is soluble in water and crystallizes from it as the anhydrous salt in the tetragonal system, as elongated prisms or needles. It is practically insoluble in ethanol. Solid monoammonium phosphate can be considered stable in practice for temperatures up to
200°C, when it decomposes into gaseous ammonia NH3 and molten phosphoric acid H3PO4. At 125°C the partial pressure of ammonia is 0.05 mm Hg. Monoammonium phosphate is industrially prepared by the exothermic reaction of phosphoric acid and ammonia.
