Chemical reactions and equations

Question:

Why do we apply paint on iron articles?

Answer:

Corrosion of metal is a redox reaction in which a metal is oxidized naturally to its ions, resulting in the partial or complete destruction of the metal. In corrosion, both oxidation and reduction take place simultaneously which leads to the formation of rust. The iron articles are painted to prevent the contact of iron with the moisture and hence, prevented the damage of iron articles.
