Description :
Densities, viscosities and ultrasonic velocities of an amino acid L-Serine at four different temperatures 288.15, 293.15, 298.15 and 303.15K for various concentrations (0.02 to 0.12) mol dm−3 in 2% of aqueous electrolytic solution have been measured. These measurements have been used to evaluate some important thermo-acoustic parameters such as Rao’s constant (R), Wada’s constant (W), molecular radius (ro), absorption coefficient (a/f2) and relaxation strength. The results are interpreted in terms of molecular interactions between the components of the mixture.
