Abstract:
Ultrasonic velocity and density of salicilaldehyde with iodine in hexane has been measured at 293.15K, 298.15K, 303.15K and 308.15K in different concentration. Ultrasonic velocity has been measured using single frequency interferometer at 2MHz (Model F-81). By using the Ultrasonic velocity (u), density (ρ) and coefficient of viscosity (η) and the other acoustical parameters adiabatic compressibility (κ), free length (L f ), interaction parameter (α), Free volume (V f ) were calculated. The addition of hexane with a mixture leads to a compact structure due to presence of dipolar type interaction. This contributes to the decrease in free volume values and the internal pressure shows an increasing trend. The results have been discussed in terms of solute-solute and solute-solvent interactions between the component and the compatibility of these methods in predicting the interactions in these mixtures has also been discussed. Key Words salicilaldehyde, iodine, hexane, Ultrasonic velocity, molecular interactions.
