Abstract: Activity coefficients of NaCl in aqueous mixture of NaCl and tetramethy lammonium chloride were determined by EMF measurements at 298. 15 Kand at eight differ ent ionic strengths from 0. 1 to 2. 5 mol/kg. The data were fitted using the Scatchard, Pitzer and Lim equations. Osmotic coefficients, excess Gibbs free energies of mixing and activity coefficients of Me4NCl were calculated at all ionic strengths.

Key words: NaCl-Me4NCl-H2O, Activity coefficient, Osmotic coefficient
