A copper coin is kept immersed in a solution of silver nitrate for some time. What will happen to the coin and the colour of the solution?

Copper is more reactive than silver therefore, when a copper coin is kept immersed in silver nitrate solution, then :

(i) A shining white deposit of silver metal is formed on the copper coin.

(ii) The colour of solution changes to blue due to the formation of copper nitrate solution.
