Why does no reaction occur when a copper strip is placed in zinc sulphate solution?

Answer and explanation

Correct answer: Copper is less reactive than zinc

In a displacement reaction, only a more reactive metal displaces a less reactive metal from its salt solution. Zinc is above copper in the reactivity series, so copper cannot displace zinc from zinc sulphate solution. Hence, no reaction occurs. Option A is incorrect because copper is less reactive than zinc. Exam tip: Compare the metals in the reactivity series to predict a displacement reaction.
