Why Fe has more reduction power then Cu ?
Fe _ [Ar]18 3d6 4s2 & Cu_ [Ar]18 3d10 4s1.
So the reduction power of Fe is more then cu, as reduction power is nothing but ability to gain electron.

Fe, it because of electrochemical series.

But the molecular formula of iron is Fe.

@Dolly,
Sodium is not used for recovering of cu because cu present in aqueous solution, if sodium is as cathode then it react with water to form sodium hydroxide, hydrogen instead to act as cathode.

Fe reduces easily copper sulphate and forms ferrous sulphate due to its reducing property when compared with copper.

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

Iron(Fe) is more reactive than Copper(Cu). So Iron displaces Copper from Copper sulfate(CuSO4) to form Iron sulfate(FeSO4).

FE is iron then what is need?

I Think Fe (Ferrum) will work best because it is not very reactive and yet it can displace copper from its sulphate. Sodium (NA or Natrium) can as well be used.
