How is the redox potential estimated in a cyclic voltammetry experiment?

The estimation of redox potential in a cyclic voltammetry experiment is effectively done by averaging the two peak potentials observed during the voltammetric scan. When a cyclic voltammetry experiment is conducted, the oxidation and reduction peaks corresponding to the redox couple can be identified at specific potentials.

By averaging the potential at which the oxidation peak occurs and the potential at which the reduction peak occurs, you obtain a value that provides a more accurate representation of the redox potential of the electroactive species. This approach takes into account the inherent behaviors of the oxidized and reduced forms of the species, leading to a more reliable measurement that reflects the equilibrium potential between the two states.

Other methods, such as taking the maximum current value, do not directly provide specific quantitative information about the redox potential itself. The current is related to the kinetics of the redox process rather than the potential. Assessing the time for the reaction is not typically relevant to redox potential and would provide little insight into the electrochemical behavior being studied. Similarly, measuring the temperature of the solution may affect the reaction kinetics and thermodynamics but does not provide a direct measure of the redox potential. Thus, averaging the peak potentials is a well-established and effective method for determining the
