Abstract

The activity coefficients for saturated aqueous KCl, CsCl and mixtures of NaCl with each of these electrolytes are calculated from solution properties using the ion interaction model as well as from the solubility. The agreement between the two sets of results for both single and mixed electrolytes is, in general, good when it is considered that the saturated solution molatities are often much higher than those whose properties were used in the evaluation of the ion interaction parameters. Also, for pure KCl (aq) the agreement is good up to 300°C, an extrapolation 50°C above the range of data on which the equations were based.
