The temperature–concentration dependences of the activity coefficient of NaCl in water-ethanol mixed solvent with 9.98, 19.98 and 39.96 wt.% of alcohol and with the solution ionic strength of up to 3 m, at 288.15, 298.15, and 318.15 K were determined by the electromotive force method using ion-selective electrodes. The results were used to estimate the interaction parameters for the Pitzer and Pitzer-Simonson models. The equivalence of the Pitzer-Simonson model and Darken’s method for the calculation of the ternary solution Gibbs energy is proved. The main sources of uncertainties in the thermodynamic properties determined by potentiometry were analyzed. It was shown that the errors in the Gibbs energies in binary water-alcohol mixtures make the main contribution to the uncertainties of the Gibbs energy values in the ternary solution calculated through approximation of the potentiometric measurements
