Zinc Reduction of Silver Ion

Zn + 2Ag+ → Zn2+ + 2Ag

Overview

Zinc reduces silver ions to metallic silver with a large cell potential of +1.56 V. Zinc is oxidized from 0 to +2 while silver is reduced from +1 to 0. This reaction proceeds vigorously due to the large potential difference between zinc and silver electrodes.

Everyday Example

Zinc's strong reducing power is exploited in zinc-silver oxide button cell batteries used in watches, hearing aids, and calculators.

Industrial Importance

Silver oxide-zinc batteries provide high energy density for miniature electronic devices. Silver recovery from waste uses zinc cementation.
