Question

what is rusting of iron?Write the chemical reaction.Write the 3 ways to prevent rusting​

Answer 1

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.

Answer 2

Explanation:

When iron is left exposed to moist air, it undergoes a chemical change leading to the formation of a brown powdered mass on the iron, leading to the occurrence of a phenomenon known as rusting.

Redox reaction

Thus, the three methods by which rusting of iron can be prevented are galvanization,applying oil , painting.
