Question

what is corrosion?How can we prevent corrosion? ​

Answer 1

Answer:

Corrosion is when a refined metal is naturally converted to a more stable form such as its oxide, hydroxide or sulphide state this leads to deterioration of the material.

Corrosion can be prevented by removing one of these conditions. Coating a metal surface with paint or enamel provides a barrier between the metal and the moisture in the environment. The process of coating a metal surface with another metal that is more likely to be oxidized is referred to as sacrificial coating.

Answer 2

Answer:

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, galvanizing, chrome plating or making alloys.
