The propagation of ultrasonic waves and the measurement of their velocity in solutions form an important tool for evaluation of various acoustical and thermo dynamical parameters which are shown to be useful in understanding the solute-solvent interaction and packing effect of solutes with solvent molecules. The thermophysical parameters density, ultrasonic velocity and viscosity have been measured for Polymer dextran in 2 (M) glycine at 308 K, at four different frequency i.e., 1 MHz, 5 MHz, 9 MHz and 12 MHz at different concentration of dextran. Using the experimental values of density, viscosity and ultrasonic velocity some of the acoustical parameters likefree volume, internal pressure, absorption coefficient or attenuation coefficient, Rao's constant and Wada's constant have been calculated keeping temperature constant at 308 K. The variation of these parameters with change in concentration and frequency has been discussed in the light of solute-solvent and solute-solute interaction.Keywords

The ultrasonic studies in solutions are great use in understanding the nature and strength of molecular interaction. The thermo-physical parameters like density, ultrasonic velocity and viscosity have been measured for dextran solution with NaOH at 303K, 308K, 313K, 318K and 323K at 9MHz frequency in different concentration of dextran solution. Using the experimental values of density, viscosity and ultrasonic velocity some of the acoustical parameters such as, acoustic impedance, adiabatic compressibility, intermolecular free length, relaxation time, Gibb's free energy have been calculated at constant frequency. The behavior of these parameters with composition of the solution has been discussed in terms of molecular interaction between the solute-solvent interaction and packing effects of solutes with solvent molecules.
