Abstract: Thermodynamic quantities ai, fi, ∆GE, ∆HE, and ∆SE were calculated on the
basis of vapour pressure measurements in molten mixtures of the type alkaline
earth metal chloride—alkali metal chloride. For the systems CaCl2 —KCl,
SrCl2—(Na, K)C1, and BaCl2 —(Na, K)Cl there is a good agreement with the
corresponding values determined by means of other methods (EMF-measurements, cryoscopy). The thermodynamic quantities calculated for the systems
RbCl—(Ca, Sr, Ba)Cl2 indicate a pronounced negative deviation from ideality.
As to the enthalpy of mixing, the experimentally determined values agree
within the experimental error with the values calculated on the basis of the
temperature dependence of the free enthalpy.
