Question

What is corrosion ? Name the factors which promote the corrosion . ​

Answer 1

Answer:

See here :-

Explanation:

• Corrosion is a natural process that converts a refined metal into a more chemically stable form such as oxide, hydroxide, or sulfide. It is the gradual destruction of materials by chemical and/or electrochemical reaction with their environment.
• There are many factors that cause corrosion. A few are - oxygen in air, temperature, the presence of chemical salts, pollution, humidity of the environment etc. 1. Pollutants like acid rain promote corrosion to a huge extent.

Answer 2

Answer:

Corrosion means a chemical destruction of metals or materials due to chemical reactions with the environment.

There are many factors that cause corrosion. A few are - oxygen in air, temperature, the presence of chemical salts, pollution, humidity of the environment etc.

1. Pollutants like acid rain promote corrosion to a huge extent. Also, the presence of other pollutants like chlorides, carbon dioxide etc. form a film on the metal by dissolving in atmospheric moisture.

2. Oxygen - Corrosion occurs in an oxygen-deficient environment and also in one where oxygen is present in excess, with the extent of corrosion being more in the latter situation than the former.
