Abstract

Apparent molar volumes of ethanol-water mixture of 10, 20, 40, and 60% (v/v) of ethanol in presence of different concentrations of potassium hydroxide were computed from measured densities of solvent mixtures and solutions at 303.15 K. Apparent molar volumes at infinite dilution have been evaluated using Masson’s equation. Viscosities of these ternary solutions were measured in order to characterize different systems. Relative strength of ion-ion and ion-solvent interactions in solutions has been interpreted from measured and estimated properties. Structure promoting and breaking properties of solute have been discussed.
