Abstract: The osmotic coefficients and activity coefficients for aqueous solution of naphtha-lene-1,5-disulfonic acid disodium and 2-naphthol-3,6-disulfonic acid sodium salt at 298.15 K have been determined by the isopiestic method. The excess Gibbs free energies were evaluated with the corresponding osmotic coefficients and activity coefficients.
