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.
