    Answer:

      Displacement of copper from its' solution by iron can prove this. Activity Place iron nail in the copper sulphate solution taken in a test tube. After sometime brown coloured copper metal is deposited on iron nail and colour of solution slowly changes to pale green due to the formation of FeSC4 solution. This proves that iron is more reactive than copper.                                                                                                                                                                                                                                       (1)
