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

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

@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.

But the molecular formula of iron is Fe.

Fe, it because of electrochemical series.

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.

It's simple displacement reaction.
cuso4+fe ->feso4+cu.
cuso4+fe ->feso4+cu.

Fe lies above cu in metal activity series so it simply displaces cuso4.

Reactivity of Fe is more than copper.

Any element higher than copper in the electrochemical series table will displace copper i.e. not copper itself.
