At different temperatures range from (303, 313, 323, 343) K for different concentrations (0.05%, 0.10%, 0.15%, 0.20%, 0.25%, 0.30%, 0.35%, & 0.40%) the basic thermodynamic properties i.e. acoustic impedance (Z), adiabatic compressibility (β), relaxation time (τ), intermolecular free length (Lf) and free volume (Vf) were calculated at 1MHz, 2MHz, 3MHz & 5MHz respectively. Solute-solvent interaction is confirmed by ultrasonic velocity and viscosity values, which increases with increase in concentration indicates stronger association between solute and solvent molecules. With rise in temperature the interaction between the solute and solvent particles decreases.
