Abstract

Conductivity and pH measurements were made on the heteropoly acids H4[PMo11VO40] and H5[PMo10V2O40] at 25° in aqueous solution to establish the stability and acid strength of the compounds. The conductivity data were treated using the Onsager-Fuoss theory to find values of Λ° and å. The data show that H4[PMo11VO40] and H5[PMo10V2O40] are strong 1:4 and 1:5 electrolytes and that H5[PMo10V2O40] is the more stable compound in solution. Hydrolytic instability of H6[PMo9V3O40] precludes a firm conclusion about the strength of this acid.
