Conductivity measurements in thionyl chloride are reported for dilute solutions of AlCl3, LiAlCl4, and the tetrapropylammonium Pr4N salts Pr4NCl, Pr4NClO4, Pr4NAlCl4. The data for electrolyte solutions having concentrations in the range of approximately 0.01 to 1 x 10 expn -5 mole dm expn -3 were fitted empirically to an equation of the Fuoss-Hsia type. In all cases except for AlCl3 ion pair formation was found to be extensive. AlCl3 solutions in thionyl chloride appear to be complex possibly owing to the formation of complex species such as Al2Cl6 and Al2Cl7-. The effect of ionic strength on the solubility of LiCl is discussed.
