Copper reacting with silver nitrate. US copper penny (1 cent coin minted in 1962) was half-submerged into a Petri dish containing a 0.2M solution of silver nitrate (AgNO3). Since copper is more reactive than silver, a single-displacement reaction occurred: Cu + AgNO3 -> Ag + Cu(NO3)2. After the coin had been in the solution for 8 min, it was removed and the photo was taken. Note metal silver that remained in the solution at the end. | |
