The osmotic coefficients and saturated vapor pressures have been calculated at the different temperatures .The experimental values of the osmotic coefficients for the Li_2SO_4-H_2O system were consistent with the values in the references. The results revealed the rules of the changing in osmotic coefficients and saturated vapor pressures with ion strengths and the molality fractions of Li_2B_4O_7 at different temperatures. The isopiestic equilibrium molalities were correlated by using the modified and the extended Zdanovskii rules for non-ideal mixtures, and obey well the Zdanovskii rules. The ion interaction parameters of Pitzer model have been determined by using the two methods for Li_2SO_4-Li_2B_4O_7-H_2O at 298.15K system.
