When an iron nail is placed in copper sulphate solution, which metal is deposited on the surface of the nail?
Answer and explanation
Correct answer: Copper
Iron is more reactive than copper, so it displaces copper from copper sulphate solution. The released copper is deposited on the iron nail. The reaction is \(\mathrm{Fe + CuSO_4 \rightarrow FeSO_4 + Cu}\). Zinc and magnesium are more reactive metals, but they are not present in the solution, so they cannot be deposited.
