Which of the following metals will displace copper from copper sulfate solution?

Iron is more reactive than copper, so it can displace copper from a copper sulfate (CuSO4) solution. This is called a displacement reaction or single replacement reaction. In the displacement reaction, iron (Fe) reacts with copper sulfate (CuSO4) solution to form iron sulfate (FeSO4) and copper (Cu): Fe + CuSO4 → FeSO4 + Cu. This reaction shows the reactivity series of metals, where iron is placed above copper, meaning iron is more reactive and can replace it from its compound.
