Question:

A silver oxide–zinc cell maintains a fairly constant voltage during discharge (1.60 V). The button form of this cell is used in watches, hearing aids, and other electronic devices. The half-reactions are
Zn(s) + 2OH(aq) → Zn(OH)2(s) + 2e
Ag2O(s) + H2O(l) + 2e → 2Ag(s) + 2OH(aq)
Identify the anode and the cathode reactions. What is the overall reaction in the voltaic cell?
