Question

What do you mean by corrosion? How can you prevent it?

Answer 1

• 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, oiling, greasing, galvanizing, chrome plating or making alloys. 
• Galvanizing is a method of protecting iron from rusting by coating them a thin layer of zinc.
