as glucose. This is perhaps because of its abundance and numerous uses. This results in the formation of sulphuric acid (H2SO4). Metals usually used as protectors in this method are zinc and magnesium since they are higher than iron in the reactivity series. This method is used in food cans and car bumpers.
