Abstract
The complex formation of cadmium(II) with ethylenediaminetetraacetate (H4Y) in aqueous solutions has been studied using scanning chronopotentiometry. It has been found that in the acid medium region (pH < 3) free (hydrated) cadmium ions and the two complex ion species CdHY− and CdY2− are in equilibrium in the case of excess cadmium ions. Scanning chronopotentiometry is shown to enable one to easily determine the equilibrium concentrations of essentially all electroactive metal ion species. This feature of the method makes it very promising for studying complex formation in solutions and for determining the stability constants of unprotonated and protonated metal complexes, especially in the case of their joint presence in the solution under investigation.
