Write an unbalanced equation for the reduction of oxygen gas under acidic conditions, in an area of the metal that functions as the cathode of an electrochemical cell. We are told that in the corrosion of iron, iron is oxidized and oxygen gas is reduced under acidic conditions. The oxidation of iron takes place in an area of the metal functioning as an anode. The reduction of oxygen gas takes place in another area of the metal functioning as a cathode. Under acidic conditions, the reduction of oxygen gas through reaction with H ions to form water can be expressed by the following unbalanced equation. (Include states-of-matter under the given conditions in your answer. Omit electrons from your answer.)
