ResumoAbstract Processes which occur upon the acidification of sodium molybdate solutions have been investigated via thermometric titration. Over a wide range of molybdate concentration (0·5-0·01 M) and ionic strength (up to 3 M), four major species are identified. The formulas correspond to HMo2O83−, Mo7O244− and MoO3. Enthalpies of association are given for each of these as well as the H3PMo12O40 species. General kinetic features of the relevant processes are also discussed.
