Lead Displacing Silver from Silver Nitrate

Pb + 2AgNO3 → Pb(NO3)2 + 2Ag

Descripción general

Lead metal displaces silver from silver nitrate solution, demonstrating that lead is more reactive than silver. Silver crystals deposit on the lead surface as shiny metallic needles. This was historically used in silver assaying and recovery processes.
