Normal molybdates are prepared by two methods (1) precipitating the insoluble metal molybdates obtained by adding the salt solution of the desired metal to a solution of sodium or potassium molybdate, and (2) neutrahzing a slurry or solution of molybdenum trioxide with the hydroxide or carbonate of the desired metal. For example, sodium molybdate, Na2Mo04, may be obtained as a dihydrate by evaporating an aqueous solution of molybdenum trioxide and sodium hydroxide. Heating the dihydrate at 100°C converts it to the anhydrous salt. Also, the normal molybdates of certain metals can be prepared by fusion of molybdenum trioxide with the desired metal oxide.
