Highest redox potential

Feb 5, 2023 · The potential is a characteristic of the chemical species to undergo an oxidation-reduction reaction. It is not the actual reaction. Rather, it is stored energy that has the ability to do work and is measured in volts; thus, the greater the voltage potential, the greater the ability and propensity to undergo a redox reaction. 6
