Question

What is meant by rusting of iron? Give two methods to prevent rusting of iron.​

Answer 1

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 (such as air containing high levels of moisture). The rusting of iron is characterized by the formation of a layer of a red, flaky substance that easily crumbles into a powder.



How to prevent rusting of iron

Exposure to outdoor conditions will increase the risk of rust, especially if the climate is rainy or humid. The best ways to prevent rust include:

Using rust resistant alloys
Design considerations
Galvanization
Bluing
Organic coating
Powder coating
Regular maintenan

Answer 2

Answer:

Rust is an iron oxide . Rusting is a common word used for corrosion of iron. If the iron is exposed in the moist air for a long time , a red oxide is formed on the iron. This is known as rusting of iron .

Two methods of prevention of rusting of iron are:-

1. Galvanisation

2. Painting

3. Oiling

4. Greasing etc.
