The electrochemical method for the determination of metal chelate stability constants by means of potentiometric measurement with a mercury electrode has been applied to EDTA complexes.of divalent metals at 30.0±0.1° in the presence of potassium nitrate.The basic principle of this method is based upon the exchange equilibria of the type.
