Question
A voltaic cell is constructed with two silver–silver chloride
electrodes, each of which is based on the following
half-reaction:
AgCl(s) + e- ------>Ag(s) + Cl-(aq)
The two half-cells have [Cl-] = 0.0150 M and [Cl-]=
2.55 M, respectively. (a) Which electrode is the cathode of
the cell? (b) What is the standard emf of the cell? (c) What
is the cell emf for the concentrations given? (d) For each
electrode, predict whether [Cl-] will increase, decrease, or
stay the same as the cell operates.
