Copper metal can reduce silver ions to metallic silver. The copper is oxidized to copper ions according to the reaction 2Ag+ (aq) + Cu (s) → Cu 2+ (aq) + 2Ag (s) A copper strip with a mass of 2.80 g is dipped into a solution of AgNO3. After some time has elapsed, the copper strip is coated with silver. The strip is removed from the solution, dried, and weighed. The coated strip has a mass of 4.60 g.
