The mean ionic activity coefficients of NaCl in a ternary system {yNaCl + (1 – y)Na2HPO4}(aq) were determined from measurements of the electromotive force (EMF) where the NaCl ionic strength fraction was y = (0.3012; 0.4015; 0.5011; 0.5988; 0.7706; 0.8997) in the range of total ionic strength of the solution Im = 0.0701–1.0161 mol kg–1 at temperature T = 298.15 K. A cell of the Na–ISE| (Formula presented.) |AgCl|Ag, type was employed for the EMF measurements. The experimental results from this work and the model of Pitzer’s were used to determine the mixing parameters. Good agreement was found between the experimental and calculated values of the mean ionic activity coefficients of NaCl with a standard deviation of fit 1.5 × 10–3. The values of the osmotic coefficients of the system {yNaCl + (1 – y)Na2HPO4}(aq) were estimated on the basis of the determined parameters and compared with literature data. The differences in the osmotic coefficients between the estimated and experimental va...lues were negligible.
