|Abstract:||Apparent molal volumes, apparent molal adiabatic compressibilities and viscosities of phenol, sodium salicylate and sodium benzoate in water have been determined at 288.15, 298.15, 308.15 and 318.15 K from density, speed of sound and efflux time measurements. These data have been utilized to determine partial molal volumes (V2°) and partial molal adiabatic compressibilities (KS,2°) at infinite dilution which have been fitted to suitable polynomials to estimate first and second derivatives with respect to temperature. Viscosity B-coefficients for the various compounds have been estimated using Jones-Dole equation. The activation energy for viscous flow has also been estimated. These parameters have been discussed in terms of solute-solvent and solute-solute interactions.|
