Abstract
Activity coefficients of KCl and NaCl were determined in the quaternary system KCl-NaCl-water-ethanol, for 10 and 20% (w/w) ethanol in the solvent, from experimental electromotive force data. The molalities varied from 0.1 mol kg−1 to near saturation and measurements were taken in the temperature range 20 to 50°C. The Pitzer-Simonson equations were used to describe the nonideal behavior of both electrolytes and the corresponding activity coefficients were determined for each solvent and temperature.
