Iron is having more reducing power than cupper.

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

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

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

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.

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.

Iron(Fe) is the right answer as Fe is more reactive than Cu.When Fe reacts with CuSo4(cupper sulphate) solution ,it gives ferrous sulphate (FeSo4) and Cu will be deposited.
CuSo4 + Fe-------> FeSo4 + Cu.
CuSo4 + Fe-------> FeSo4 + Cu.

Fe is more reactive than cu thats why cu is displace from copper sulpate solution and thus formation of ferrous sulphate solution is made containing brown colour of doposit layer.

Reduction potential of Fe is higher than that of Cu.

Fe is a anthode while cu is a cathode.
