Thermodynamic mixing functions are calculated for a number of binary alkali halide melts over an entire range of concentration following Blum`s exact solution of the mean spherical model for charged hard spheres with arbitrary diameters and the Mansoori et al. approximation for hard sphere contributions to free energy. Estimated results and experimental data are compared and discussed. Satisfactory agreement is shown for dependencies of molar density and sound velocity on concentration, especially for relative ones with respect to additive. This model describes only positive departures of the mixing enthalpy from the ideal behavior and its values are regularly higher for such systems as NaCl-NaBr, KF-CsF, and KCl-KI. Calculated results for the values of sound velocity deviate no more than a few percent for NaCl-NaBr, NaCl-NaI, and NaBr-KBr.
