Conductivity and dielectric properties of aqueous cadmium sulfate solutions

Abstract

The results of measurements of concn.- and temp.-dependences of electrolyte conductance and of high frequency permittivity of aq. solns. of CdSO4 are compared on the basis of the chem. model of electrolyte solns. Both methods yield results which are compatible with regard to ion assocn. and hydration and with thermodn. data. The coulombic and noncoulombic parts of the enthalpy and entropy of ion-pair formation are of the same order of magnitude.
