Fused Salt Concentration Cells with Transference Transport Numbers of Molten Alkali Chloride and Silver Chloride Mixtures

Abstract

Abstract By emf measurements on concentration cells with silver electrodes the transport numbers of molten NaCl + AgCl, KCl + AgCl, RbCl + AgCl, and CsCl + AgCl have been determined over the whole concentration range at temperatures between 800 and 1075 K. All systems show an "inversion point" (equal cation mobilities), which shifts to higher silver chloride concentrations with higher temperatures. At high dilutions the diluted cation is always the less mobile one.
