CuSo4+Fe == Feso4 + cu it's an displacement reaction.

The electrochemical series shows that Cu is having high reduction potential than Fe. So that there occurs a displacement reaction when Fe is exposed to a solution containing Cu.

This will make Fe to replace Cu.

If Fe more reactive than Cu. That's why this reaction take place.

Then why not Na? Please explain me.

Iron is more reactive than copper but I think Na is better to displace cu from CuSO4.
