A study on volumetric and thermo-acoustic properties of amino-acetic acid in aqueous solution

Abstract

In the present study, the ultrasonic velocity, density measurements have been carried out for binary mixture of amino-acetic acid in aqueous sodium chloride in the concentration range of (0.02-0.2 M) at 283K, 288K, 293K, 298K, having the frequency at 2MHz using ultrasonic Interferometer. Experimental data have been used to calculated the thermo-acoustical parameters adiabatic compressibility (β), Wada's constant (W), Rao's constant(R), Molar volume (Vm), change in adiabatic compressibility(∆β), relative change in adiabatic compressibility(∆β/β) and Thermal conductivity, to investigate the nature and strength of molecular interaction in binary mixture of (amino-acetic acid + NaCl + H₂O). The result are discuss in the existing of the solvent - solvent interaction shows that result in attractive force for the structure making tendency and solute - solute interaction show that result in electro-strictive force for the structure braking tendency.
