Answer 2

When iron nail is dipped in copper sulphate solution, than iron sulphate solution and copper solution and copper metal are formed.

In this reaction, iron displaces copper from copper sulphate solution. The deep blue colour of copper sulphate fades due to the formation of light green solution of iron sulphate.
