Why does a displacement reaction not 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, a more reactive metal can displace 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. If option B were true, displacement would be possible; however, copper is actually less reactive than zinc.
