Abstract: The conductivities of LiBr, LiCl, and LiNO3 in methanol, ethanol, 1-propanol, and 2-propanol (with electrolyte concentrations <0.08 mol•L?1) were determined at 298.15 K, 313.15 K, and 323.15 K at atmosphere pressure separately by using a conductivity meter. The conductivity data were correlated with Foss-Chen-Justice (FCJ) equation and the limiting molar conductivities were obtained. The mean ionic activity coefficients of the salts in the organic solvents were calculated according to the Debye-Hückel limiting law and Onsager-Falkenhangen equations. The calculated results were compared with those activity coefficients in literature.
