Fe is the right answer because ferrous is more reactive than copper due to which it will displace the copper from copper sulphate solution and the solution will become green in color due to the formation of ferrous sulphate and a brown layer of deposit layer will form on the iron metal.

There are two elements Na and Fe. Because both element is high level of metal activity series. Na is more react than Fe. But the answer is Fe. Because Na reacts with water. So it's not useful for recover than Fe.

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

In the activity series, iron is more reactive element than copper. So iron can separate copper from copper sulfate.

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

Iron is having more reducing power than cupper.

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

Iron is less reactive than Cu according to the reactivity series table.
That is why iron is used to recover in the copper sulphate solution.
That is why iron is used to recover in the copper sulphate solution.

According to metal activity series, Fe is more reactive than Cu that means no reaction should take place and a less reactive element cannot replace a more reactive element and hence no reaction should take place. Then how come Cu replaces Fe?
