The density, viscosity and ultrasonic velocity have been measured for binary mixture of gallic acid with ethanol and acetone of fixed equal volumes of the components at temperatures of 298 K. The experimental data have been used to calculate some acoustic and thermodynamic parameters like adiabatic compressibility, free length, acoustic impedance, relaxation time and internal pressure. From the properties of the acoustical parameters, the nature and the strength of interactions in these binary systems are discussed. Increase in velocity and decrease in adiabatic compressibility shows strong association and interaction in the constituents' molecules. Some possible reasons on the increase or decrease of acoustic and thermodynamic parameters with temperature change are presented.Keywords

The generated ultrasonic wave for a particular frequency (2 MHz) affects the molecular interaction of binary mixture of ellagic acid in acetone. Ellagic acid is a powerful bioactive compound with many potential pharmacological and industrial applications. Ellagic acid is a polyphenolic compound in fruits and berries. The experimental data have been used to compute some acoustic and thermodynamic parameters such as adiabatic compressibility, intermolecular free length, free volume, relaxation time and acoustic impedance at different temperature over the entire composition range. The non-linear variations of these derived acoustical parameters with different concentration of the solute explained on the basis of structural changes occurring in a solution. The variation in ultrasonic velocity and other parameters play an important role in understanding solute-solvent interaction between the constituent molecules are presented with some possible reasons.Keywords
