Solution
Rusting:
- Rusting of iron refers to the formation of rust i.e. a mixture of hydrated iron oxide on the surface of iron objects when it comes in contact with the moisture and air.
- It is a chemical change.
The methods by which rusting of iron can be prevented are discussed below:
1. Galvanization:
- Galvanization is a method of protecting steel and iron from rusting by coating them with a thin layer of zinc.
- Even if the zinc coating is broken, the galvanized item is protected against rusting.
- To avoid rusting, the iron pipes that carry water in our homes are galvanized.
2. Painting:
- Painting is the method by which rusting of iron can be prevented.
- It prevents the direct interaction of iron from air and moisture.
Thus, the two methods by which rusting of iron can be prevented are galvanization and painting.
