VARIATION OF CONCENTRATION OF DEXTRAN WITH GLYCINE AT 308 K AND AT FREQUENCY 5MHZ
Abstract
The density (?) viscosity (?) and ultrasonic speed (U), at 308 K have been measured in the systems of different
concentration of dextran with glycine in aqueous medium. The ultrasonic seed have been measured by using
ultrasonic interferometer at frequency of 5MHz in different concentration of dextran with glycine in aqueous
medium. The acoustic parameters such as free volume, internal pressure, absorption coefficient, Raos constant
and Wadas constant are calculated using the measured parameters ?, ? and U. The variation of acoustic
parameters with different concentration of dextran with glycine leads to the analysis of molecular motion and
various types of inter-molecular interaction and their strength of the constituent between solute (dextran) and
solvent (glycine 2(M))
