Question

The reaction of iron nail with copper sulphate solution is ................. reaction.(A)combination (B)decomposition (C)displacement (D)double displacement

Answer 1

The reaction of iron nail with copper sulphate solution is displacement reaction.

Answer 2

Answer: Option (C) is the correct answer.

Explanation:

When an iron nail is dipped into a copper sulfate solution then iron being more reactive will displace copper from copper sulfate solution.

The chemical reaction equation for the reaction is as follows.

         $Fe(s) + CuSO_{4}(aq) \rightarrow FeSO_{4}(aq) + Cu(s)$

Therefore, when an atom displaces another atom of a compound then it is known as displacement reaction.

Thus, we can conclude that the reaction of iron nail with copper sulphate solution is displacement reaction.
