Thermo-acoustic Investigations on L-valine in Aqueous Salt

Author(s): Giratkar VA, Lanjewar RB, Gadegone SM, Patil KC

The ultrasonic velocity (u), density (ρ) and viscosity (η) of an amino acid L-Valine of various concentrations in 2% of NaCl solutions have been measured. From these experimentally measured parameters thermodynamic parameters such as adiabatic compressibility ( ), intermolecular free length ( ), acoustic impedance (Z), internal pressure ( ), relaxation time ( , Gibb’s free energy ( ), free volume ( ), Vander Waal’s constant (b), Rao constant (R), Wada constant (W), molecular radius (ro) absorption coefficient (a/f2), relaxation strength (r), available volume (Va), volume expansivity ( ), reduced volume ( ????) and enthalpy (ΔH) were calculated. It was found that there is certain degree of variation in these parameters with change in concentration and temperature. The variations of acoustic parameters with concentration and temperature indicate the existence of intermolecular interaction in the present systems.
