Correlation of solubilities for the image system with the Pitzer model at 15, 25, 50, and image

Solubility data of the NaCl+LiCl+H2O system have been measured at 15 ring operatorC. These data along with others recorded in the literature, at 25, 50, and 100 ring operatorC, have been correlated using the Pitzer model and the extended Debye–Hückel model. The latter was used to determine the activity and osmotic coefficients of the binary systems NaCl+H2O and LiCl+H2O. The results obtained in this work show that the calculated solubility values are in good agreement with the experimental ones.
