Think of the reaction between zinc and copper. Instead of placing a piece of zinc directly into a solution containing copper, we can form a cell where solid pieces of zinc and copper are placed in two different solutions such as sodium nitrate. The two solids are called electrodes.

6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

Zinc reacting with lead nitrate in a soft gel to form lead crystals. This is a displacement reaction. When a metal from the electrochemical series is mixed with the ions of a metal lower down in the series, the atoms of the more reactive metal push their electrons on to ions of the less reactive metal.
