Density, Electrical Conductivity, and Viscosity of Manganese (II) Chloride and Tetra‐n‐Butylammonium Halides

Abstract

The temperature dependence of equivalent conductances, A, and fluidities, r of mixtures of MnC12 in molten tetra-n-butylammonium halides, TBAX (X ----C1 and I) has been described in terms of the Adam-Gibbs and the modified Doolittle expressions. Such a dependence of Walden products has also been discussed in terms of three similar parameter equations based on the Doolittle expression. The composition dependence of electrical conductivity and viscosity of both the systems has successfully been described by the composition dependent equation based on the configurational entropy model. The better applicability of such an equation for this purpose has been emphasized in glass-forming binary molten mixtures. Furthermore, variation in the preexponential factor, Ay of the Adam-Gibbs expression has been found to be a linear function of To.
