✦ Synopsis

The osmotic coefficients of the mixed electrolyte solution yK SO q 1 y y Mg NO aq 2 4 3 2 have been measured by the isopiestic method, at the temperature T s 298.15 K. The activity Ž . coefficients of K SO and Mg NO were calculated by Scatchard's neutral-electrolyte 2 4 3 2 method and by Pitzer and Kim's treatment for mixed electrolyte solutions. The results are used for calculation of the excess Gibbs energy as a function of ionic strength and ionic-strength fraction of K SO , and also as a test of Zdanovskii's rule of linearity. ᮊ 1998 2 4
