Abstract

Precise molar conductances of Bu<sub>4</sub>NBPh<sub>4</sub>, Bu<sub>4</sub>NI, Bu<sub>4</sub>NNO<sub>3</sub>, AgNO<sub>3</sub>, LiNO<sub>3</sub>, NaBPh<sub>4</sub> and KI have been measured in acetone (Ac), dimethylsulphoxide (DMSO) and Ac + DMSO mixtures over the whole solvent composition range at 25°C. The conductance data has been analysed by computer using Shedlovsky conductance equation. Limiting ionic conductances have been calculated by using Gill’s model. Evaluation of solvated radii of Li<sup>+</sup>, Na<sup>+</sup>, K<sup>+</sup> and Ag<sup>+</sup> ions in Ac + DMSO mixtures shows strong preferential solvation for Li<sup>+</sup> ion by DMSO. Na<sup>+</sup> and Ag<sup>+</sup> ions are found to be preferentially solvated by DMSO in Ac-rich region and by Ac in DMSO rich regions. K<sup>+</sup>, NO<sub>3</sub><sup>-</sup> and I<sup>-</sup> ions show no preferential solvation in Ac + DMSO mixtures.
