Effect of DMF on the solvation behaviour of BiCl₃in CH₃OH and CH₃CN: A conductometric study

Abstract

The effect of addition of dimethyl formamide on the conductivity and solvation behaviour of BiCl₃ in CH₃OH and CH₃CN at four different temperatures has been reported. In both

the solvents, the conductivity is found to decrease and the solvation is found to increase on addition of DMF at all temperatures. Kraus-Bray and Shedlovsky conductivity models

have been used to evaluate the limiting molar conductance, dissociation and association constants. Ion pair formation constant and triple Ion constant have also been computed. Walden product and thermodynamic parameters are also reported. Solvation number of the species of BiCl₃ has been calculated in pure solvents by the mobility method.
