Abstract
The freezing points of aqueous mixtures of sodium chloride and magnesium chloride have been measured in the range of ionic strengths from 0.1 to 3.5 mole-kg−1. The composition dependence of the excess Gibbs function is considered from the standpoint of the Scatchard ion-component treatment of electrolyte solutions. The ion-component equations predict the osmotic coefficients of the mixtures from the single-salt results with a maximum error of less than 1%. Values of Friedman's parameterw o at the freezing points of the solutions are compared with isopiestic and theoretical values at 298 K.
