Abstract
Density (ρ), refractive index (n), conductivity (κ) and viscosity (ɳ) measurements have been carried out for binary mixtures of imidazolium based ionic liquids with ethanol at 298.15 K. Excess molar volumes have been calculated from experimental data and was fitted by Redlich-Kister equation. The density and refractive index increase with increasing ionic liquid (IL) concentration. Addition of IL leads to increased conductivity initially within these mixtures, which is subsequently followed by gradual decrease in IL-rich region showing the restricted ion mobility and enhanced interactions within these mixtures. Viscosity was found to be increase gradually with increasing IL concentration. It has been observed that solubility parameters, dielectric constant and nature of anions of ILs being used play a vital role in determining the fate of resultant properties.
