摘要：

The activity coefficients of NaCl were estimated by measuring the EMFs of the cell Na ion-selective electrode \ NaCl(m(A)), NaOAc(m(B)) \ Ag/AgCl at four ionic strengths, i.e., 0.5, 1.0, 2.0, and 3.0 mol/kg and at temperatures 25, 35, and 45-degrees-C. The results were analyzed in terms of Harned's rule, the Pitzer and Rush-Johnson-Scatchard treatments. Osmotic coefficients and excess free energies of mixing were calculated at all ionic strengths and temperatures studied.
