Thermodynamic Properties of LiCL in Dimethyl Sulfoxide

EMF measurements were performed at 25°, 30°, and 35°C on the cell Pt(s)/Li(s)/LiCl(solution in DMSO)/TlCl(s)/Tl(Hg)(l)/Pt(s) For concentrations up to 0.12M, the activity coefficients at each temperature may be represented satisfactorily by Guggenheim's extension of the Debye-Hückel equation. The partial molal Gibbs free energy, entropy and enthalpy of transfer of LiCL from DMSO to water have been calculated to be −4.93 kcal/mole, +24.8 cal/°K-mole and +2.61 kcal/mole, respectively.
