Question

copper displaces zinc from zinc sulphate solution.​

Answer 1

Explanation:

• Copper is less reactive than zinc and so placed below zinc in the reactivity or electron affinity series of metals. A metal which is less reactive, cannot displace a more reactive metal from a solution of its salt. Hence, copper cannot displace zinc from its salt solution.

Answer 2

Answer:

Explanation:

Zinc dust reacts with copper sulphate solution,

forming zinc sulphate and copper. Zinc displaces

copper from copper sulphate and an aqueous

solution of zinc sulphate is formed.

Zn(s) + CuSO4(aq) → ZnSO4(aq) + Cu(s) ↓
