Why do we apply paint on iron articles?

Text Solution

Verified by Experts

By coating paint over iron articles, the contact of moist air with iron is cut off. So, moist air cannot attack on the surface of iron articles and there is no risk of rusting (corrosion of iron). Thus, iron articles can be protected from damage for many years.
