On the impedance of galvanic cells XXI. Analysis of the electrode impedance in the case of a non-reversible electrode reaction with specific adsorption of the electroactive species; appl

Abstract

The impedance of the Pb2+/Pb(Hg) electrode has been measured in order to demonstrate the effect of specific adsorption of the electroactive species. The simple randles circuit is not in accordance with the experimental facts and therefore an attempt has been made to interpret them in terms of the theory of SEnda And Delahay, Delahay's new charge separation, model. The procedure for evaluating the parameters is fully outlined. It is found that the experimental data fit both models.
