Which type of reaction occurs when an iron nail is placed in copper sulphate solution?
Answer and explanation
Correct answer: Displacement reaction
Iron is more reactive than copper. Therefore, iron displaces copper from copper sulphate solution to form iron sulphate: \(\mathrm{Fe + CuSO_4 \rightarrow FeSO_4 + Cu}\). A reaction in which a more reactive metal replaces a less reactive metal from its salt solution is a displacement reaction. It is not a combination reaction because the reactants do not form a single product.
