Ultrasonic Study of Ternary Liquid Mixture Containing Substituted Benzene

Abstract

The Ultrasonic velocity, density, and viscosity have been measured for ternary mixture of N-N dimethyl formamide (DMF), Cyclohexane and Nitrobenzene at different temperatures (288K, 298K and 308K) for a constant frequency (2 MHz). Acoustic parameters like adiabatic compressibility (β), free length (Lf), free volume (Vf), available volume (Va), Vander Waals constant (b), internal pressure (πi), relaxation time (τ), acoustic impedance (Z), and Gibb’s free energy (ΔG) for the solution have been computed. The excess values of the parameters are also evaluated and discussed.
