THEORY OF IRREVERSIBLE POLAROGRAPHIC WAVES. CASE OF TWO CONSECUTIVE ELECTROCHEMICAL REACTIONS

Abstract

Solutions were derived for 2 boundary-value problems corresponding to electrode processes controlled by semi-infinite linear diffusion and by the rates of 2 consecutive electrochemical reactions. Two cases were considered: (1) two consecutive irreversible electrochemical reactions, and (2) electrode reactions involving a potential determining step. The adaptation of the solutions for linear diffusion to the case of the dropping Hg electrode was discussed. It was shown that mechanisms based on the assumptions in case 2 cannot be used in the interpretation of irreversible polarographic waves. Considerations are presented on the significance of diagrams showing the variations of half-wave potentials with a parameter characterizing a substance in a series of organic substances. Application is made to the reduction of chromate ion in 1 M NaOH; considerations indicate this reaction proceeds with the intermediate formation of Cr4+. (See also AD13646).
