Hello mate !!!!!!

Here is your answer ...

When we put iron nail in copper sulphate solution (blue in colour). Because iron is more reactive than copper so it displaces the copper from copper sulphate solution.

After a few hours we obtain a nail with copper covering and iron sulphate solution(green in colour).

ANSWER :

Fe(s)+CuSO4⟶Cu(s)+FeSO4

When an iron nail is dipped in copper sulphate solution, a brown coating of copper is formed on the surface of iron and the colour of copper sulphate solution changes from blue to light green. This reaction shows that iron is more reactive than copper as it displaces copper from its solution and iron passes into solution as Fe2+ ions and ferrous sulphate solution is formed.
