| Summary: | Isopiestic vapor pressure measurements have been made to determine some thermodynamic properties of the system: water-sodium chloride-calcium chloride at 25 °C. Equations are derived for the activity coefficient of each salt in the presence of the other when the total ionic strength is kept constant. The limiting conditions in very dilute solutions are considered and “trace” activity coefficients calculated. A comparison with previous work is made. The excess free energy of mixing is calculated. |
