According to activity series, iron is more reactive then copper hence iron will displace copper from its aqueous solution.

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

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

Fe and Na both are above Cu in electro chemical series. Then why doesnt Na replace copper from its own solution?
Kanhaiya said:

Then Na also should have reduced Cu because it lies way ahead of Cu in the electrochemical series, just like Fe.

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

A/c to electrochemical series, Iron is more reactive than Copper so it reduces Copper sulphate to get copper.

As the fe and cu both lying in the same group. And although the electronegativity of fe is higher than cu.

If Fe more reactive than Cu. That's why this reaction take place.
Then why not Na? Please explain me.
Then why not Na? Please explain me.

Thanks for your answer Navneeth.Fe is more reactive than copper so it reduces CuSO4 to copper .
