A cell is constructed by immersing a strip of iron in a 1.0 M {eq}Fe(NO_3)_2 {/eq} solution and a strip of gold in a 1.0 M {eq}AuNO_3 {/eq} solution. The circuit is completed by a wire and a salt bridge. As the cell operates, the strip of gold gains mass (only gold), and the concentration of gold ions in the solution around the gold strip decreases, while the strip of iron loses mass, and the concentration of iron ions increases in the solution around the iron strip. Write the equations for the half-reactions that occur at the cathode and at the anode.

Electrochemical Cell:

Electrochemical cells can be voltaic or electrolytic cells based on whether the reaction is spontaneous or non-spontaneous. The overall cell potential value can be calculated to determine spontaneity and is obtained from the reduction potential of individual electrodes.
