摘要：
The complex formation reaction of silver(I) with glycinate ion in aqueous ethanol and dimethyl sulfoxide solutions of variable compositions was studied by potentiometric titration at 298 K. The stabilities of Ag(I) glycinate complexes were found to increase with the increasing content of the organic cosolvent. The contribution of Delta G degrees of the reagent resolvation to the change in the Gibbs energy of the complex formation reaction was estimated using the literature data. The change in the ligand solvate state was shown to give the main contribution to the stability of the title complexes in water-organic solvents.
