Copper Displacing Silver from Silver Nitrate

Cu + 2AgNO3 → Cu(NO3)2 + 2Ag

Visão geral

Copper metal displaces silver from silver nitrate solution because copper is more reactive than silver. Silver crystals grow on the copper surface in beautiful tree-like formations (dendrites), while the solution turns blue from dissolved copper nitrate. This produces one of the most visually stunning chemistry demonstrations.
