Studies on complexation equilibria between water-soluble hydrazones which consist of 5-nitro-2-pyridylhydrazine and heterocyclic ketones and divalent metal ions.
Complexation equilibria between five water-soluble hydrazones which consist of 5-nitro-2-pyridylhydrazine and heterocyclic ketones and divalent metal ions have been studied spectrophotometrically. Equilibrium constants of the complexation reactions and overall formation constants of the resultant complexes have been determined and species of the complexes clarified.
