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.

Abstract


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.
