Because iron is more reactive than copper. So, it is used to displace copper.

Fe is more reactive than copper so it reduces copper sulphate to copper.

Fe recover copper becoz the iron lyes below in the electromegnatic table

Please clearify the answer. Copper doesnt come under magnatic property.

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

Fe is more reactive than Cu, and so will displace copper in solution.

Fe is higher reactive than cu so it displaces fe in fe so4.

Harsh said:   1 decade ago
It's simple displacement reaction.

cuso4+fe ->feso4+cu.

Oxidation state of mercury can be +2, why can't be Hg then?

@Eliza.

The most electronegative elements are nonmetals.
