Which statement about the reaction \(\mathrm{Fe + CuSO_4 \rightarrow FeSO_4 + Cu}\) is correct?
Answer and explanation
Correct answer: Iron displaces copper from its salt solution because iron is more reactive than copper.
Iron \(\mathrm{Fe}\) is above copper \(\mathrm{Cu}\) in the reactivity series. Therefore, iron displaces copper from \(\mathrm{CuSO_4}\) solution to form \(\mathrm{FeSO_4}\) and \(\mathrm{Cu}\). Hence, this is a displacement reaction, not a decomposition or neutralisation reaction.
