AbstractThe linear isopiestic relation has been used together with a well-known thermodynamic equation to establish a new predictive equation for freezing point depression. This equation can provide predictions for multicomponent solutions conforming to the linear isopiestic relation using only information on the corresponding binary subsystems. The predictive capability of the equation has been tested by comparing with the experimental data at 25 degreesC reported in the literature and particularly those of Pathwardhan and Kumar. The systems used are NaCl-MgCl2-H2O, NaCl-BaCl2-H2O, NaCl-CaCl2-H2O, LiCl-NaCl-H2O, LiCl-KCl-H2O, LiCl-CsCl-H2O, NaCl-KCl-H2O, and NaBr-KBr-H2O. The predictions of the two equations agree well with the experimental data although our new equation is, in general, better.
