Zinc displaces copper from its salt solution, but copper does not displace zinc from its salt solution. What is the correct conclusion?

Answer and explanation

Correct answer: Zinc is more reactive than copper

In a displacement reaction, a more reactive metal displaces a less reactive metal from its salt solution. For example, zinc displaces copper from copper(II) sulfate solution: \(\mathrm{Zn + CuSO_4 \rightarrow ZnSO_4 + Cu}\). Therefore, zinc is more reactive than copper. Option B is incorrect because copper cannot displace zinc from a zinc salt solution.
