Volumetric studies of aqueous solutions of monosodium salts of some aliphatic dicarboxylic acids at 298.15Â K. A new method of data analysis

► The densities of aqueous solutions of monosodium salts of the dicarboxylic acids have been measured. ► A new method for determining the values of partial molar volume of the electrolyte has been proposed. ► The values of partial molar volumes of electrolytes have been determined. ► The variations of Vϕ0 values with aliphatic chain length of analyzed salts were determined.
