_______________________

This is a displacement reaction.
In this activity we can observe changes at the end that
•Iron nail turns into brown
•Blue colour of copper sulphate fades

The chemical reaction is as follows::

Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s)

Here the iron displaces copper in the solution because iron is more reactive than copper.
