Statement 1: Corrosion of cans is more complicated than that of tin and iron alone. Depending on whether the tin forms a complex or not, it acts as the anode or cathode. Statement 2: In the corrosion process, if hydrogen is not evolved, it exerts a back pressure and opposes further oxidation of iron.
