  • Abstract

    Densities and viscosities of ternary mixtures of KCl, KBr and KI in different percentage 10, 20, 40 and 60% v/v ethanol-water for different concentrations of potassium salts were measured at 303.15 K. Data obtained has been used to understand the ion-ion and ion-solvent interactions in solution. Effect of percentage of ethanol and concentrations of salts on strengthening or weakening of these interactions has been evaluated. Apparent molar volumes have also been estimated from density data of different systems. Ion-solvent interactions have been interpreted in terms of the partial molar volumes which were determined from Massonís relation.
