Take a solution of copper sulphate in a beaker. Add some iron nails to it. Keep for sometime. You will notice that the blue colour of copper sulphate solution fades away. A brown deposit is formed on the iron nails.

Here since iron is more reactive that copper,it displaces copper from its salt solution of copper sulphate and forms iron sulphate . Copper metal deposits on the iron nail.

Fe(s) + CuSO4(aq) FeSO4(aq) + Cu(s)
