Diffusion potentials on a porous diaphragm separating molten alkali-metal chlorides from alkali-metal bromides and iodides
Cells in which porous diaphragms separate alkali-metal halides are frequently used in the practice of electrochemical investigations with molten salts. At present, the authors maintain that the literature does not offer any reliable data on the transport numbers of halide anions in molten mixtures of alkali-metal chlorides and bromides or chlorides and iodides, which precludes the determination of the sign and the calculation of the value of the diffusion potential in these melts. Diffusion potentials can be determined with a high accuracy by directly measuring the emf of cells both with transfer and without transfer. Their electromotive action is based on the same reactions involving the displacement of bromine or iodine by chlorine from the molten alkali-metal bromides or iodides.
