Abstract

The mean molal stoichiometric activity coefficients have been measured for NaCl at 325 and 350 degree C and for KCl and CaCl//2 from 200 to 350 degree C using the static vapor pressure method. Differential vapor pressure measurements made using a strain-gauge transducer proved to be rapid and accurate. A simple method is presented that factors the activity coefficient into three parts corresponding to long-range electrostatic ion-ion interactions, hydration, and association; this reproduces experimental values with reasonable accuracy.
