“…By these combined effects α also decreases in a solution. The decrease in isentropic compressibility and isothermal compressibility was caused due to a decrease in coefficient of thermal expansion which is due to a decrease in density [30][31]. From Table 3, the heat capacity ratio decreases to a lesser extent by increasing concentration but with rise of temperature notable fall of heat capacity ratio can be observed from the graph.…”

The densities (ρ), and ultrasonic velocities (u) of 1-Butyl-2, 3-dimethylimmidazolium chloride [ ] in aqueous solutions of Tetran-butyl ammonium bromide over the complete range of concentrations has been calculated at different temperatures T= (298.15 to 313)K. Experimentally obtained values of ρ and u were used to calculate the parameters like acoustic impedance (Z), isentropic compressibility (β S ), molar sound velocity (Rao's constant) (R), molar compressibility (Wada's constant)(W), intermolecular free length (L f ), co-efficient of thermal expansion (α), heat capacity ratio (γ), isothermal compressibility (β T ) and nonlinearity parameters (B/A). The final results obtained were analyzed to understand the ion-solvent and ion-ion interaction so taking place in the solutions. Further, the effect of temperature on the ion solvent interactions was discussed. Ion-solvent interactions are affected by the thermo acoustical properties and by nonlinear parameters. Keywords: Ion-solvent interactions; Tetra-n-butyl ammonium bromide; 1-Butyl-2,3-dimethyl imidazolium chloride; Wada's constant; Rao's constant; ultrasonic velocity. MATERIALS AND METHODS Materials.The ionic liquid, 1-Butyl-2,3-dimethylimidazolium chloride, [ ] , with mass fraction purity ≥ 0.985, Tetra-nbutyl ammonium bromide, TBAB with mass fraction purity ≥ 0.99 were imported from Sigma-Aldrich (U.S.A.). The IL,[ ] , was dried overnight to eliminate moisture content under vacuum at 343.15 K. Later than Karl Fischer analysis, the water content was found to be 351ppm. Tetra butyl ammonium bromide was purified by recrystallization from acetone, and all the required substances were desiccated by keeping in vacuum desiccators over for about 2-3 days before its application. The complete information of the compounds taken in this study is presented in Table 1. Instruments and methods.Electronic balance of model ABJ-220-4NM (KERN, Germany) was used to record the mass of solute and solvents with a precision of 10 -4 g. The solutions of concentration 0.08, 0.10, and 0.12mol dm -3 were prepared by weighing the required amount of electrolyte in a weighing bottle and then dissolving it in the required amount of solvent in a 250 mL measuring flask. Rest of the solutions of concentration 0.001, 0.005, 0.01, 0.02, 0.04, and 0.06 mol dm -3 were prepared by dilution. The conversion of
