The thermal decompositions of pure and mixed manganese carbonate and ammonium molybdate tetrahydrate in molar ratios of 3:1, 1:1 and1:3 were studied by DTA and TG techniques.
USP Monographs: Ammonium Molybdate
Insoluble substances— Dissolve 20 g in 200 mL of water in a beaker, heat to boiling, cover, and heat on a steam bath for 1 hour. Filter the hot solution through a tared filtering crucible, wash the insoluble residue with hot water, and dry at 105 for 2 hours: the weight of the residue so obtained does not exceed 1 mg (0.005%).
