Abstract

Excess volume (V-E), excess viscosity (eta(E)), excess free energy of activation of viscous flow (G(*E)), and Grunberg-Nissan interaction parameter (d) of binary mixtures N,N dimethylacetamide (DMA) + ethanol have been calculated from the viscosities (eta) measured at 298.15, 303.15, 308.15, 313.15and 318.15 K over the whole composition range. All the excess functions studied are found to be negative over the entire range of composition indicating strong interaction between DMA and ethanol molecules. Densities (rho) and ultrasonic velocities (u) of lithium nitrate in DMA + ethanol mixtures have been measured at above mentioned temperatures as function of DMA mol fraction. From these experimental data, isentropic compressibility (k(s)), intermolecular free length (L-f), and relative association (R-A) of LiNO3 + DMA + ethanol ternary mixtures have been computed. These properties are usedto discuss ion-solvent interaction and selective solvation of ions by the component molecules of the liquid mixture.
