Voltaic Cells I - The Copper-Zinc Cell | Blausen Medical
When a strip of zinc metal is immersed in an aqueous Cu2+ sulfate solution, electrons are transferred from zinc to the Cu2+ ions. Copper metal deposits on the zinc strip and collects at the bottom of the flask. Zinc atoms are oxidized to Zn2+ ions, which enter the solution. This spontaneous oxidation reduction reaction is summarized in the chemical equation shown. The spontaneous copper-zinc
Penny reactions - Chemistry Resource
Rub the penny against a hard surface so that it exposes the shiny silvery metal under the copper layer. The shiny silvery metal is zinc. Immerse two pennies, side-by-side, in the salt/vinegar solution. The penny with the zinc exposed (on the right) will never get shiny.
