Question

what do you understand by corrosion ? write any two methods to reduce corrosion of irons​

Answer 1

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.

Answer 2

Answer:

Corrosion is when a refined metal is naturally converted to a more stable form, such as its oxides or hydroxides state and this leads to deterioration of the material. Galvanisation is a process of applying a layer of zinc on a metal to prevent corrosion. Applying oil and paint helps to reduce corrosion.
