Explain why, iron sheets are coated with zinc.

Answer :

To prevent iron from corrosion we coat it with zinc. This so because, Zinc is a quite reactive metal. The action of air on zinc metal forms a very thin coating of zinc oxide all over it, which is hard and impervious to air and hence prevents the further corrosion of zinc metal as well as the iron below it.
