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 liquidus curves in the binary equilibrium phase diagrams of the systems, ZrCl2–MCl, and ZrCl3–MCl, where M is potassium or sodium, have been determined where possible. The electrochemical properties of the dilute solutions of zirconium di-, tri-, and tetra-chlorides, in the temperature range 670 °C to 750 °C, were investigated by reversible electromotive force measurements. From the results various equilibria between zirconium metal and the solutions of zirconium tri- and tetra-chlorides, respectively, were determined. Activity calculations indicate that zirconium tetrachloride is heavily complexed in these melts.
