摘要：

In the paper, thermodynamic properties of sysytems NaCl-MgCl2-water-isopropanol were determined by electromotive force measurements.The emf reading were carried out at the different molalities of NaCl and MgCl2 in the isopropanol-water mixtures at 298.15K.While the Pitzer model was adopted to describe the behavior of electrolytes,the activity coefficients, E-Theta and the related model parameters were calculated in different ratios of isopropanol-water mixtures. Except that the free energies of transfer of sodium chloride from water to isopropanol-water mixtures were calculated and Pitzer parameters theta(NaCl) and psi(NaMgCl) were determined. The results found activity coefficients of NaCl obey Harned rule in a mixed solvent.
