उत्तर

  1. The type of reaction occurring in the given diagram is displacement reaction.
    \[\ce{\underset{\text{Iron}}{Fe_{(s)}} + \underset{\text{Copper sulphate}}{CuSO_{4(aq)}} -> \underset{\text{Ferrous sulphate}}{FeSO_{4(aq)}} + \underset{\text{Copper}}{Cu_{(s)}}}\]
  2. Observations:
  • The blue colour of the solution will turn to green in test tube A and copper coating will form on iron nail because iron displaces copper from copper sulphate.
  • The reaction will not occur in test tube B because iron is more reactive than copper.
