A copper coin is kept in a solution of silver nitrate for some time. What will happen to the coin and the colour of the solution?
We know that copper is more reactive than silver, so it will displace silver from its salt solution. Cu (s) + 2AgNO3 (aq) → Cu(NO3)2 (aq) + 2Ag (s) So, the solution will turn blue due to the formation of copper nitrate.
