✓
Answer
Take strips of zinc and copper and two test tubes with copper sulphate and zinc sulphate solution. Add zinc strip in copper sulphate solution and copper strip in zinc sulphate solution.
Observation: In the test tube with zinc strip in copper sulphate solution shows that blue colour of copper sulphate solution fades. The other test tube will not show any change. This proves that zinc is more reactive than copper.
