✓
Answer
Iron being more reactive displaces copper from copper sulphate solution. In this reaction, the blue colour of copper sulphate fades and there is deposition of the iron nail.$\text{Iron(Fe) + Copper sulphate(CuSO}_4)\\\rightarrow\text{Iron sulphate (FeSO}_4)+\text{Copper(Cu)}$ Concept insight: iron is more reactive than copper.
