3. Take an fresh Iron Nail and tie it with a thread(u can use forcep instead of thread for easy handling). Leave it into the Copper sulphate solution.<br>

4. Keep this for about 15-20 minutes.<br>

5. After 20 minutes we see the deposition of Copper over iron nail.

The process of losing electrons is called "Oxidation" and the process of gaining electrons is called "Reduction". These two processes taking place simultaneously hence we call it as '''“Redox reaction”'''. Here, Iron loses electrons whereas Copper gains electrons. So, Iron is more reactive than Copper hence, it displaces Copper from Copper sulphate solution.
''' CuSO4 + Fe → FeSO4 + Cu '''
