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.
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
