Chat OnlineCuSO 4 (aq) Zn (s) → Cu (s) ZnSO 4 (aq) is an example of displacement reaction.. A displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. In the above reaction Zn is added to the solution of copper sulphate and Zn displaces Cu from its salt solution. This is because zinc is a more reactive metal that displaces
