Prevention of Rusting of Iron

The rusting of iron involves the process: Fe → Fe2+ + 2e-. The oxidation state of iron changes due to oxygen atom in the presence of water. The ferrous ions get oxidized to ferric ions in presence of moisture and air also generating hydroxyl ions and yielding ferric hydroxide. 4Fe2+ + O2+ 2H2O →4Fe3+ + 4OH-.
