網頁2024年8月14日 · In the corrosion process, iron metal acts as the anode in a galvanic cell and is oxidized to Fe 2+; oxygen is reduced to water at the cathode. The relevant reactions are as follows: at cathode: O 2(g) + 4H + (aq) + 4e − 2H 2O(l) with Eo SRP = 1.23 V. at anode: Fe(s) Fe2 + (aq) + 2e − with Eo SRP = − 0.45V. 網頁A36 Steel. 1018 Steel.
