Abstract In this paper, the conductivities of NaBr in methanol, ethanol, 1propanol, 2propanol, NaCl and KBr in methanol, ethanol system (solution concentration within 01 mol·L-1) were determined at 29815 K, 31315 K and 32315 K at atmosphere pressure respectively. The mean ion activity coefficients of NaBr, NaCl and KBr in various organic solvents were calculated according to DebyeHücker limiting law and OnsagerFalkenhangen equations. The effects of concentration and temperature on activity coefficients of electrolyte solutions were discussed. The calculated results were compared with those of NaBr in ethanol, NaCl in methanol and KBr in methanol reported in literature. The results show that the experimental data obtained by conductivity method have good agreement with data in literature.
