摘要：

We report osmotic and activity coefficients of aqueous sodium sulfate solutions. The osmotic coefficients were determined at 40 degrees C by the isopiestic method. Sodium chloride served as the isopiestic standard. The molality ranges covered in this study correspond to about 0.2-3.0. The activity coefficients were calculated from the parameters obtained by fitting the Hamer-Wu and Fitter equations to the experimental osmotic coefficients.
