Abstract: The dissociation model of the electrical conductivity of molten salt mixtures, based on the assumption of an incomplete dissociation of electrolyte components was applied in some binary reciprocal univalent systems. The systems of alkali halides and the systems of alkali halide and silver halide were verified. It was found that the dissociation model of the electrical conductivity of molten salt mixtures may be successfully applied in the reciprocal systems as well. From the standpoint of the physical interpretation the correctness of the calculation is conditioned by the consistency and the correctness of the molar conductivity values, especially by the correctness of the value of the standard Gibbs energy of the exchange reaction. In the reciprocal systems the most dissociated is always the stable pair of salts. The dissociation degrees of all components are higher than 0.5 in all systems studied.
