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

If Fe more reactive than Cu. That's why this reaction take place.
Then why not Na? Please explain me.

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.
This will make Fe to replace Cu.

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

A/c to electrochemical series, Iron is more reactive than Copper so it reduces Copper sulphate to get copper.

Fe is more reactive than copper so it reduces copper sulphate to copper.

Ag & Hg are less reactive than copper.
Adding sodium - it would ignite before it could react.
Fe is more reactive than copper and would displace it to combine with the sulfate ion, thereby separating copper.

In the electrochemical series, Na is higher than Fe.
Na is should be the answer.
Na is should be the answer.

I think sodium is the right answer, as it is above iron in periodic which has greater ability to react with sulphate to displace copper.
