Expert Answer:

Iron is more active metal than copper. When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution and forms iron sulphate, which is green in colour.

Therefore, the blue colour of copper sulphate solution fades and green colour appears.
