Description :
Measurement of ultrasonic velocity and its related properties in the liquid mixture play an important role to study physic-chemical behavior of the solution. Acoustic and thermodynamic properties determine from ultrasonic velocity and related properties which provide qualitative information about molecular interactions in liquid mixture. Ultrasonic velocity, density and viscosity of ampicillin sodium were measured at different concentration at 303.15 temperatures and at 2MHz frequency. From data thermodynamic parameters such as adiabatic compressibility, intermolecular free length, specific acoustic impedance, relative association, relaxation time, Rao’s constant and Wada’s constant were evaluated. The effect of concentrations on molecular interaction in aqueous solution of ampicillin sodium was interpreted in terms of thermodynamic parameters.
