The equivalent conductivity of the potassium chloride was measured at various temperatures between 25 and 40℃ in ethanol-water mixed solvent system. Density, viscosity, and dielectric constant data are also reported for the mixed solvent.
Limiting equivalent conductivity and Walden product as a function of solvent composition and temperature are reported. The interactions between solvent-solvent and ion-solvent are discussed.
Maxima of ⋀₀η₀ are found for the potassium chloride solutions in 0.1 mole fraction of ethanol. It is assumed that the maxima of ⋀₀η₀ correspond to an association of water and ethanol with higher degree of hydration than the association of viscosity.
