Conductance of electrolyte solutions. A modified expression for its concentration dependence

Abstract

Fuoss and Hsia have recalculated the relaxation field of the Fuoss and Onsager (F–O) theory for electrolytic conductance since the F–O equation failed to fit experimental data with sufficient accuracy. The resulting expression, which is complicated, was used in the present work to calculate the coefficients J₁ and J₂ of the equation, Λ=Λ₀–Sc^½+Ec ln c+J₁c–J₂c. The new expression is superior to the previous Fuoss and Onsager expression and the discrepancies between the latter theory and that of Pitts are much reduced when the new J₁ and J₂ coefficients are used.
