Abstract Osmotic coefficients for aqueous mixtures of sodium chloride with benzyltrimethylammonium chloride, BzMe3NCl, obtained by the gravimetric isopiestic vapor pressure comparison method are interpreted with the McKay-Perring transform, with the Scatchard neutral electrolyte treatment, and with the Pitzer ion-component equations. Molal ionic and mean ionic activity coefficients for Na+ and Cl− ions and for NaCl, respectively, in these mixtures at unit total ionic strength also were determined with an electrochemical cell. The excess free energy chenges ΔGex on mixing NaCl with BzMe3NCl were estimated and employed to gain an insight into the relative importance of like and unlike cation-cation interactions.
