The mean activity coefficients of LiCl in LiCl-Li2SO4-H2O system were determine at 25?and ionic strength 0.01-6.0 mol/kg. Measurements were made by using an electrochem. cell with a Li ion-selective electrode. The experimental mean activity coefficients obey Harned's rule and Pitzer's equation and agree with results obtained by isopiestic method. Mean activity coefficients of Li2SO4 and the osmotic coefficients and excess free energies of mixing were also calculated
