Magnesium Paramolybdate, 3MgO.7MoO3.20H2O, may be prepared by the action of nitric acid on magnesium molybdate in solution; upon evaporation, small transparent prisms are obtained.
The salt is readily soluble in water. It is stable at atmospheric temperature, and becomes anhydrous on heating.
From a solution containing ammonium paramolybdate (1 molecule) and magnesium nitrate (2 molecules) colourless crystals have been obtained, which may be formulated (NH4)3.Mg.H5[H2(MoO4)6].6H2O. |
