1.	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» Solution :Copper is more reactive than silver. Hence, it displaces silver from the silver NITRATE solution according to the given reaction. `underset("copper")(Cu(s))+underset("Silver nitrate")(2AgNO_(3)(aq))rarrunderset("Copper(II) nitrate")(Cu(NO_(3))_(2)(aq))+underset("Silver")(2Ag(s))` 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.
