Concept explainers

Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.

Question

Analyze and answer the following.
1. A galvanic cell consists of Mg anode in a 1.0 M Mg(NO,), and Al cathode in
a 1.0 M AI(NO,, solution with NaCl as the electrolyte in the salt bridge.
2. Agalvanic cell is made of Tin anode in 1.0 M SnCl, and Iron cathode in a 1.0
M FeCl, solution with NaNO, as the electrolyte in the salt bridge.
For each of the two cells,
a. sketch and label the galvanic cell;
b. write the half-cell equations;
c. write and balance the overall cell reaction;
d. calculate the standard emf of this cell at 25°C; and
e. determine whether the reaction is spontaneous or nonspontaneous.
