Abstract
The enthalpy change on cooling molten and solid salts and their mixtures from temperatures as high as 850º down to 26.9º has been measured by means of a Bunsen-type fusion calorimeter. The enthalpy of formation of solid mixtures has also been measured using a water solution calorimeter. From the combined results, heats of mixing have been determined for the molten salt systems investigated. In each system, with the exception of CdCl2 + PbCl2, the process of mixing is exothermic and the relative magnitude of the results can be explained by the formation of complex ions in the systems CdC12 +NaCl, CdCl2 +KCl, PbCl2 +KCl, and CdI2 +KI. Complex ions have not been detected in the other systems.Keywords
