Molybdic acid and its organic complexes—I Some studies on molybdic acid prepared by ion exchange

An ion exchange method is described for the preparation of molybdic acid in more concentrated solution than that obtained by dissolution of yellow molybdic acid, MoO32H2O. This acid has been examined potentiometrically and conductometrically by titration with sodium hydroxide and the resultant titration curves have been found to depend on the concentration of the molybdic acid solution used. Evaporation to dryness of the molybdic acid solution prepared by ion exchange yields a colourless glass. Commercial molybdic acid has also been examined.
