Last updated at April 16, 2024 by

The Chemical Reaction Involved in the Corrosion of Iron Metal is that of:

  1. Oxidation as well as Displacement
  2. Reduction as well as Combination
  3. Oxidation as well as Combination
  4. Reduction as well as Displacement

 

Answer

  1. Oxidation as well as combination reactions

 

Explanation : 

In the chemical reaction involved in corrosion of iron metal -

Iron + Oxygen + Water → Hydrated Iron Oxide

4Fe + 3O 2 + 2xH 2 O → 2Fe 2 O 3 . xH 2 O

 

It is an oxidation reaction as Iron gains Oxygen while forming Iron Oxide.

It is a combination reaction as more than 2 substances (Iron, Oxygen and Water) react to form a single product.
