Investigation of physical parameters for aqueous amino acid and glycol ether system at 303.15 K and at various concentration

Density ( ), viscosity (), and ultrasonic velocity (u) have been measured for aqueous glycine and glycol ether at 0.1 to 1 concentrations and at 303.15 K temperatures. Physical parameters as acoustical impedance (z), adiabatic compressibility (β), relaxation time (τ), Rao’s constant (R), Wada’s constant (W), free volume (Vf), molar volume (Vm), intermolecular free length (Lf) have been obtained from experimental data it shows intermolecular interaction of the present system. The measured and calculated thermodynamic parameters have been discussed in terms of interaction may be solute-solute or solutesolvent or solvent-solvent type.
