Abstract: Activity coefficient values for NaCl in ethanol-water mixtures containing 20, 40, 60, 70, 80 and 90 weight % ethanol are calculated from the emf for the galvanic cell Na−glass|NaCl(m),H2O(100−Y),EtOH(Y),AgCl|Ag in which the weight % of the corresponding solvent is indicated in parenthesis. The results obtained are analyzed by using different theoretical models. Chemical models which take into account the presence of ion pairs in solutions of high ethanol content are also used. There is good agreement between the results obtained from all the models.
