Synthesis

Ammonium phosphomolybdate can be made by heating ammonium orthomolybdate combined with phosphoric acid and nitric acid, yielding ammonium nitrate, water, and a yellow precipitate of ammonium phosphomolybdate is obtained.

12(NH4)2MoO4 + H3PO4 + 21 HNO3 → (NH4)3PMo12O40↓ + 21 NH4NO3 + 12 H2O
