      A copper coin was kept dipped in silver nitrate solution for a few hours/days. What will happen to the copper coin? What will happen to the colour of the solution?

    Answer:

                      Copper is more reactive than silver. Hence, it displaces silver from the silver nitrate solution according to the reaction.                                       The silver thus formed is deposited on the surface of copper, thereby giving it a white shining appearance. The solution becomes blue due to the formation of copper nitrate.
