A Study of Acoustical parameters of Sodium Acetate with Amides in Ethanol at Different Temperatures

The ultrasonic velocity, density and viscosity have been measured for the ternary mixtures Sodium acetate with secondary and tertiary amides in Ethanol at 303K, 313K and 323K. The experimental data have been used to calculate the acoustical parameters namely adiabatic compressibility (β), free length (Lf), free volume (Vf), internal pressure (πi), Viscous relaxation time (τ) and Acoustic impedance (Z). From the obtained values, molecular interactions have been determined through hydrogen bonding between solute and solvent liquid mixtures.
