Abstract
Osmotic coefficients for the CaCl2-H2O system between 25 and 250°C and from the dilute region to solid saturation or beyond (i.e., to ≈ 12 mCaCl2 at the lowest temperature and ≈32 mCaCl2 at the highest) have been correlated using the following permutations and modifications of the basic Pitzer ion-interaction equation: (1) the basic Pitzer equation, (2) the Pitzer equation augmented by an ionic strength-dependent third virial contribution, (3) the Pitzer equation together with equilibria involving the formation of CaCl+ and CaCl20, and (4) the simultaneous combination of all of the above. The effectiveness, accuracy, and practicality of each approach are reviewed.
