Question

What is rusting of Iron? Suggest two ways by which it can be prevent.​

Answer 1

Answer:

Rusting of iron refers to the formation of rust, a mixture of iron oxides, on the surface of iron objects or structures. This rust is formed from a redox reaction between oxygen and iron in an environment containing water.

Prevention method of rusting

Many different types of coatings can be applied to the surface of the exposed metal in order to prevent corrosion. Common examples of coatings that prevent corrosion include paints, wax tapes, and varnish.

Galvanization is the process of applying a protective layer of zinc on a metal. It is a very common method of preventing the rusting of iron.

Providing the metals with an electric charge can help inhibit the electrochemical reactions that lead to rusting.

Answer 2

Definition of Rusting :

Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated Ferric Oxide, which we see as rust. This rust is formed from a redox reaction between oxygen and iron in an environment containing water (such as air containing high levels of moisture).

Two ways by which rusting can be prevented :

(a) The rusting of iron can be prevented by painting, oiling, greasing or varnishing its surface.

(b) Galvanisation is another method of protecting iron from rusting by coating it with a thin layer of zinc.
