Abstract

The intermolecular free-length of 1-butyl-2,3-dimethylimidazolium chloride [bdmim]Cl in pure water as well as in tetra-n-butyl ammonium bromide (TBAB) + water at different concentrations of solute and at T = (298.15 to 313.15) K have been evaluated by making use of ultrasonic and thermoacoustical parameters followed by a comparative study. To accomplish this objective, thermoacoustical parameters for the above said solutions have been calculated. These parameters have been used to determine intermolecular free-length (Lf) for the solutions under study. The values of Lf obtained by thermoacoustical approach were tallied with the values obtained by well-known ultrasonic method (Schaaffs method). To the best of our understanding, this study is an innovative attempt in the determination of inter-molecular free-length present in the investigated solutions by making use of ultrasonic approach.
