Question

What happens when
a)Zn reacts with Copper sulphate solution
b) Copper reacts with Iron sulphate solution.
Write the balanced chemical equations involved in each case

Answer 1

a) Zinc is more reactive than copper. That's why it will displace copper from the solution and react with sulphate ions to form zinc sulphate and copper metal.

Zn + CuSO₄ → ZnSO₄ + Cu

b) Copper does not react with ferrous sulfate solution, because copper is below iron on the series and can't displace iron ions from solution.
