what are corrosion and how will you prevent it
Answers
Answer:
Hi your answer is as follows
Explanation:
When some metals are exposed to moisture, acids etc., they tarnish due to the formation of respective metal oxide on their surface. This process is called corrosion. Corrosion can be prevented by painting the surface, oiling, greasing, galvanising, chrome plating or making alloys.

Answer:
Explanation:
Corrosion is one of the most common phenomena that we observe in our daily lives. Corrosion is the deterioration of a metal as a result of chemical reactions between it and the surrounding environment. It is a natural irreversible process. Some common examples of corrosion are rusting, blackening of silver metals, etc.
Ways to prevent corrosion:
1. Electroplating : It is the process by which a metal is coated with a thin layer of another metal (II) using electrolysis.
2. Galvanization : This process involves coating iron with a thin layer of zinc.
3. Painting and Greasing : Providing a layer of paint or grease on the metal can prevent the exposure of the metal with the external environment thereby preventing corrosion.
hope it helps!
