Seethalakshmi.K ^[2] | Jasmine Vasantha Rani.E ^[2]

Abstract: The study of ions in liquids and solutions is a part of chemical Physics. The passage of ultrasonic waves through solutions and liquids disturb the equilibrium between the solvent molecules. The measurement of ultrasonic velocities in liquids and solutions is found to be one of the convenient tools for studying the physico-chemical behavior in solution. It provides very useful information related to intermolecular interaction. In the present investigation, an attempt has been made to evaluate various thermo dynamical parameters of imidazolium salt in non-aqueous medium at different concentrations. The ultrasonic technique provides a powerful, effective and reliable tool to investigate properties of the solution. The fundamental properties namely ultrasonic velocity, density and viscosity are determined experimentally. The measured data are used to calculate the internal pressure and free volume. The results obtained from ultrasonic technique elucidate the various intermolecular interactions in the solution and the results are also compared with FT-IR spectrum.
