When iron metal is exposed to oxygen and water, a familiar result is observed—rust. The rusting process consists of sev-eral steps. In the first step, iron is oxidized to iron(II) ions, Fe2+, and oxygen from the air is reduced to hydroxide ions, OH–. This oxidation–reduction reaction takes place via two separate half-reactions (Equations ...
