Ion-selective electrodes were used to measure the activity coefficients at 298.2 K of individual ions in aqueous solutions of NaCl and NaBr up to of 5 molal and of KCl up to 4 molal. The mean ionic activity coefficients of NaCl, NaBr, and KC1, obtained from the values of the activity coefficients of
The Liu-Harvey-Prausnitz model (1989a) for electrolyte solutions with ion-specific parameters is extended to simultaneously correlating the mean ionic activity coefficient data for 55 aqueous electrolytes including the H,SO,/H,O system up to the H,SO, concentration of 76 m. With only 1.6 adjustable
