Explanation:

Answer

The rusting of iron can be prevented by the following methods:

(1) Iron surface is coated with paint. It is a temporary solution. The iron surface is shielded from oxygen and moisture.

(2) Iron is coated with another metal such as zinc. The process is called galvanising. Zinc is stronger reducing agent than iron and hence preferentially oxidised.

(3) An alloy of Fe with Cr is formed. This alloy is stainless steel. It reduces the tendency of iron to oxidise.
