Half-reaction for the reduction of oxygen: O2 + 4e- + 4H+ → 2H2O E0O/4OH-=+1.23 V As we have seen in the reactions involving hydrogen ions. Supplier of hydrogen ions is water. With an increase pH to 9-10, corrosion reaction practically stops. Therefore, the reaction occurs in the presence of oxygen dissolved in water, the water takes on the role of the electrolyte.
