Question

write any two ways to prevent iron from corrosion

Answer 1

There are many ways to prevent rusting of Iron:

Galvanization

Galvanization is a process in which the Iron sheets are coated with a layer of Zinc which prevents rusting. Zinc gets oxidized more readily than Iron. So, the Iron remains protected.

Painting

Painting the Iron surface will create a barrier between the Iron and the atmosphere, which will protect the Iron from rusting.

Electroplating

Iron sheets can be electroplated with a metal which is more reactive than Iron, so that instead of the Iron getting oxidized, the other metal gets oxidized (because it is more reactive).

Answer 2

2 ways of prevent corrosion.
1.By Mixing Iron with Zinc and Lead.
2.By painting with plastic paint.
