Abstract:

Transference numbers of the cations relative to the chloride ion in molten mixtures of alkali chloride - cerium chloride were determined from emf measurements on concentration cells with transference of the type -H2, HClg-CMClAl203MCl,CeCl3C-HCl,H2g, where M is Li, Na, or K. The cells were operated with a mixture of hydrogen and hydrogen chloride gases instead of chlorine gas to minimize the possibility, if any, of the oxidation of cerous chloride to ceric chloride. The emf measurements were carried out at 850C and results are presented over the entire composition range of the systems studied. It was also shown that, in these mixtures, the alkali ions possess a relatively larger mobility than the cerous ion.
