Question:

A voltaic cell is constructed with two Zn2+ - Zn electrodes. The two half-cells have [Zn2+] = 1.8 M and [Zn2+] = 1.00 × 10-2 M, respectively.
(a) Which electrode is the anode 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 [Zn2+] will increase, decrease, or stay the same as the cell operates.
