Viscometric and ultrasonic studies of Glycine has been carried out in Methanol + water and Ethanol + water co-solvents at different temperatures 30, 35 and 40oC respectively. From these experimental data, derived thermodynamic parameters such as the isentropic compressibility (s), intermolecular free length (Lf), acoustic impedance (z), molar compressibility (w), molar sound velocity (R) and apparent molar compressibility (k) have been computed using the standard relations. The results have been analyzed on the basis of variations in thermodynamic parameters. The variations in Ultrasonic velocity and adiabatic compressibility with concentrations in both systems show a similar trend of increasing ultrasonic velocity and decreasing in adiabatic compressibility of the constituent electrolytes at different temperatures. This is due to complex formation and coordinate covalent bond formation between the molecules of the liquid mixtures. The results are discussed in terms of structure – making or structure – breaking effects of amino
acids in the mixture.
