Abstract
The correlation between the polarographic behavior of depolarizing substances and their chemical structure has been worked out from two points of view, one being expressed in terms of the half-wave potential, and the other in terms of their kinetic data of the electrode reaction.
In a reversible electrode process the half-wave potential relates to the approximate value of the standard redox potential. A more detailed investigation in this respect is the relevancy of the half-wave potential to the lowest unoccupied π orbital. On the other hand, the treatment of the kinetic parameters with respect to the chemical structure mostly remained only with a simple expression of the reversibility or of the irreversibility.
The present authors measured the more detailed kinetic parameters of the electrode reaction of cobalt (III) complexes of the [Co(NO2)n(NH3)m](3-n)+ type.
