Physico-Chemical Studies of some Bivalent Electrolytes in Aqueous Mixtures of Dimethysulphoxide Mixtures at Different Temperatures by Transport Property Measurements.

摘要

Conductances and viscosities of some bivalent electrolytes ha ve been measured in water, dimethyl sulphoxide (DMSO) and their binary mixtures over whole solvent composition range at 25,35 and 45 deg C, The limiting molar conductance (Aj, limiting ionic conductance (λ_i~o), Walden products (λ_i~oη_o), solvated radii (R_i), viscosity A and B-coefficient values ha valuated. The studies have been made to investigate the effect of nature of electrolyte, solvent composition and temperature on the solvation behaviour of ions in DMSO and DMSO + water mixtures. The results have been discussed in terms of salvation behaviour of bivalent ions.
