Zinc displaces copper from a copper sulphate solution, but copper does not displace zinc from a zinc sulphate solution. What conclusion can be drawn about the reactivity of zinc and copper?
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. Since zinc displaces copper from copper sulphate, zinc is more reactive than copper. In contrast, copper cannot displace zinc from zinc sulphate because copper is less reactive.
