Electrochemical studies of molten salt mixtures. I. The electromotive forces of concentration cells with transference containing the molten electrolytesystems PbBr₂ + CsBr, PbBr₂ + RbBr, and PbBr₂ + KBr

Abstract

The e.m.f.'s of concentration cells with transference (i.e. with liquid junction), containing the binary molten salt systems, PbBr₂+CsBr, PbBr₂+RbBr, and PbBr₂+KBr, have been measured as functions of temperature and electrolyte composition. The cell e.m.f.'s have been found to vary with temperature and electrolyte composition in a discontinuous manner: graphs of cell e.m.f. against temperature are in general a number of intersecting straight lines, as are graphs of cell e.m.f. against the negative logarithm of the mole fraction of one component.
