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
In the present study we use the hygrometric method for the determination of relative humidities of aqueous electrolyte solutions. The relative humidities of KCl(aq), Na 2 SO 4 (aq), and NaNO 3 (aq) have been measured for different molalities and at temperatures from (278.15 to 323.15) K. The data on
