Class 10th Lakhmir Singh & Manjit Kaur - Chemistry 3. Metal and Non-Metal

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.
