Abstract
Density (ρ), viscosity (η), and ultrasonic velocity (U) of binary mixtures of aliphatic solvents like dimethylformamide (DMF) and dimethylsulfoxide (DMSO) with aromatic solvents viz. chlorobenzene (CB), bromobenzene (BB), and nitrobenzene (NB) have been determined at 313 K. These parameters were used to calculate the adiabatic compressibility (β), intermolecular free length (Lf), molar volume (Vm), and acoustic impedance (Z). From the experimental data excess molar volume (VmE), excess intermolecular free length (LfE)), excess adiabatic compressibility (βE), and excess acoustic impedance (ZE) have been computed. The excess values were correlated using Redlich–Kister polynomial equation to obtain their coefficients and standard deviations (σ).
