Abstract: The conductivity of dilute aqueous solutions of CaCl2, CaCl2NaCl, CaCl2KCl have been determined at 298.15 K. The limiting molar conductances, association constants and ion size are evaluated by means of the FuossOnsager equation. The ion association of CaCl2 has been discussed, and the mixtures have been correlated as pseudo binary electrolytes.

Key words: Electrolytes, Ion association, Calcium chloride, Sodium chloride, Potassium chloride
