In the mixed electrolyte solution {xK2SO4 + (1-x)MgSO4}(aq), the osmotic coefficients have been measured by the isopiestic method at the temperature 298.15 K. Scatchard's neutral-electrolyte method and Pitzer-Kim's treatment were used for the activity coefficients of the K2SO4 and MgSO4 calculation.
