Take iron nails and copper sulphate solution to prove it.
First put the iron nails in the copper sulphate solution and leave it undisturbed for some time.


Observation

After some time you will observe that the colour of copper sulphaye solution which was blue in colour changed to green and a brown coloured layer get deposited on iron nails.

We know thta iron is more reactive than copper so following reaction must take place
Fe+CuSO4=>FeSO4 + Cu


The blue colour of solution changed to green as a new substance iron sulphate is formed and the brown coloured layer on the nail is copper.
