Colour of copper sulphate does not change when iron nail is dipped into it.
✒
☆ When an iron nail immersed in the solution of copper sulphate then iron displaces copper from the solution of copper sulphate because iron is more reactive than copper.
✔ Therefore copper sulphate solution colour changes from blue to pale green.
Iron is more reactive than copper sulphate and it displaces it.
✒
☆ We know that Iron is placed above copper in the activity series. Thus iron is more reactive than copper.
✔ Iron displaces copper ions from an aqueous solution of copper sulphate. It is a single displacement reaction of one metal by another metal.
