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 concentration given? (d) For each electrode, predict whether [Cl-] will increase, decrease, or stay the same as the cell operates.
