Electromotive Force Measurements

Electromotive force measurements on the ZnCl2–ACl systems where A = K, Rb, and Cs were made using cells of the type[Formula: see text]in the temperature range 450° to 800 °C. The partial molar free energies, enthalpies, and excess entropies have been determined from the temperature dependence of the emf results. These thermodynamic properties exhibit increasing negative departure from ideality as the basicity of the alkali metal salt increases. The results are interpreted in terms of an acid–base reaction and are discussed in relation to current models.

The electrode potentials of the system Th, ThCl4 (KCl, NaCl) were measured at various concentrations of thorium chloride, and at temperatures between 670 °C and 850 °C, using a silver – silver chloride reference electrode. It was shown by a direct gravimetric method that the reaction,Th(metal) + ThCl4(melt) = 2ThCl2(in melt),postulated by previous investigators, did not take place.The activity coefficients, and the other partial molal properties of the solutions of ThCl4, in the equimolar mixture of potassium and sodium chlorides, were calculated as a function of temperature from the e.m.f. measurements.
