cuso4+Fe=Feso4+cu This is chemical reaction. cu give 2+ electron and so4 accept this electron.

Fe is more electronegative than Cu so it will displace Cu according to displacement reaction.

Sodium also is more reactive than copper. Why can't it displace copper from its solution?

Its because iron displaces copper sulphate as iron is more reactive metal than copper.

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

The solution first at colour blue. After reacting it with Fe we get green colour now.

Refer the electrochemical series position of both the copper. So the answer is iron.

Actually both sodium and iron are able to displace copper from its solution. Right?

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

Iron oxidation state is two so iron accept sulphate ion according to mechanism.
