The stability of calcium chloride ion pairs in aqueous

The speciation of calcium in chloride solutions has been investigated between 100 and 360°C by measuring the solubility of AgCl in HCl-CaCl 2 solutions in which chloride varies from 0.3 to 3.0 m and calcium is maintained constant at 0.1 m. Cumulative equilibrium formation constants of calcium chloride ion pairs were evaluated using a non-linear least squares procedure.
