High reduction potential.

The standard reduction potential can be determined by subtracting the standard reduction potential for the reaction occurring at the anode from the standard reduction potential for the reaction occurring at the cathode. The minus sign is necessary because oxidation is the reverse of reduction. E ∘ cell = E ∘ cathode − E ∘ anode.Jul 23, 2020 · 2. Electrode potential is the potential difference between the electrode and the surrounding electrolyte. If the potential of the cathode is positive this means that the potential of the electrode is greater than the potential of the electrolyte, which means that the electrons will flow from the electrolyte to the cathode. 1.5: Factors that Influence Reduction Potential. In general, the ions of very late transition metals -- those towards the right-hand end of the transition metal block, such as copper, silver and gold -- have high reduction potentials. In other words, their ions are easily reduced.Feb 5, 2023 · The potential is a characteristic of the chemical species to undergo an oxidation-reduction reaction. It is not the actual reaction.
