Copper reacting with silver nitrate. US copper penny (1 cent coin minted in 1981) was put into a Petri dish. 0.2M solution of silver nitrate (AgNO3) was then added. Since copper is more reactive than silver, a single-displacement reaction occurred: Cu + AgNO3 -> Ag + Cu(NO3)2. In this sequence top frame was taken before the solution was added. Middle frame was taken after the coin had been in the solution for 1 min. Bottom frame was taken after the coin had been in the solution for 7 min. Note the solution becomes slightly bluish due to Cu2+ ions. | |
