Procedure

An aqueous solution of phosphomolybdic acid is prepared by heating 360 parts (2.5 moles) of molybdenum trioxide, 24 parts of 85% phosphoric acid and 2,000 parts of water at boiling for three hours, then filtering through filter paper and washing the residue with 150 parts of water. The total volume of the resulting solution is reduced to yield 921 parts of solution containing 19.37% molybdenum.
