In this part, the densities of sodium benzoate, sodium nitrobenzoate, sodium chlorobenzoate and sodium methylbenzoate in DMFwater mixed solvents have been measured at 298.15K with an Anton Paar Model 55 densimeter. From these densities, apparent molar volumes and partial molar volumes have been calculated, transfer volumes from water to DMF-water mixtures and substituent contributions to the transfer volumes have also been obtained. Solvent and substituent effects are discussed in detail. The Scaled Partical Theory has been applied to the ternary solutions to evaluate the partial molar volumes of cavity formation and the volumes change associated with solute-solvent interaction.
