The osmotic coefficients of aqueous mixtures of Li_2SO_4 and MgSO_4 have been measured from 1.4 to 13.5 mol·(kg)~(-1) at 25 ℃ by using the isopiestic method. In the ranges of 0.2—8.7 and 0.6—12.7 mol·(kg)~(-1) the osmotic coefficients of Li_2SO_4 and MgSO_4 were also reported respectively. Ion interaction parameters of Pitzer model and Scatchard model have been calculated from these measurements. In comparison with Mckay-Perring method, the osmotic and activity coefficients for Li_2SO_4-MgSO_4 mixtures are fairly reliably represented by both Pitzer's equation and Scatchard's neutral electrolyte equation. The predicted solubilities for this system using Pitzer's approach show od agreement with experimental results.
