The mean activity coefficients of NaCl in ethylene glycol-water mixtures were determined in the range of w = 0.10 to 0.40 ethylene glycol at 288.15, 298.15 and 308.15 K using potentiometric measurements. The Pitzer and extended Debye-Htickel equations were used to describe the nonideal behavior of the electrolyte. Osmotic coefficients and the standard Gibbs energy of NaCl-ethylene glycol-water were calculated.
