Abstract

Physical Properties like density (ρ), ultrasonic speed (u), viscosity (ŋ) of binary liquid mixture of Nitromethane+ DMSO have been carried out over the different range of composition at 313.15 K. these parameters are further used to compute compressibility Ks, acoustic impedance, relaxation time and their excess parameters like excess molar volume (VE), excess viscosity ŋE, excess velocity (uE), excess compressibility (KsE), excess acoustic impedance. The excess parameters have been fitted to the Redlich-Kister polynomial equation. The experimental results have been discussed in detailed in terms of solute-solvent interactions.
