Densities and molar volumes for the molten salt systems ZnBr₂ + KBr, CdI₂ + NaI and CdI₂ + CsI

Abstract

Densities of binary mixtures of ZnBr₂ + KBr, CdI₂ + NaI and CdI₂ + CsI, have been measured by an Archimedian method over a wide range of temperature. Results have been expressed in terms of simple linear equations in temperature. Molar volumes for the systems have excess values in the ZnBr₂ + KBr and CdI₂ + CsI systems but not to such an extent in the CdI₂+NaI system. The excess molar volumes are related to the possible formation of complex ions in the systems concerned.
