Question

A voltaic cell is constructed with two silver-silver chloride electrodes, where the half-reaction is

Answer 1

The silver chloride electrode usually functions as a redox electrode where the equilibrium is achieved between silver and its salt (silver chloride).
The half reaction for this electrode is as follow:
AgCl(s)+e−→Ag(s)+Cl−(aq) where:
(s) refers to solid state
(aq) refers to the aqueous state and
e- is the electron
