Abstract : SALTS, ELECTRIC POTENTIALThe thermodynamics of lithium chloride-potassium chloride mixtures were studied over the concentration range x(LiCl) = 0.3 - 0.9 at 640C from the emf measurements on concentration cells with transference of the type: Cl2(g)-C/LiCl, KCl//LiCl/C-Cl2(g). A quartz spiral tube filled with alumina powder was used to establish the liquid junction between the two compartments. From a knowledge of transference numbers of the cations relative to the chloride ion, it was possible to determine the relative partial free energy of mixing and excess free energy of mixing of lithium chloride in the mixtures. The thermodynamic values for potassium chloride were obtained by using the Gibbs-Duhem equation. Both lithium chloride and potassium chloride show a slight negative deviation from ideality in their mixtures over the whole concentration range. (Author)
