A galvanic cell consists of one half-cell that contains Ag(
s) and Ag
+(
aq), and one half-cell that contains Pb(
s) and Pb
2+(
aq). What species are produced at the electrodes under standard conditions?
Ag+(aq) + e- → Ag(s) | E° = +0.80 V |
Pb2+(aq) + 2 e- → Pb(s) | E° = -0.13 V |
◦ Ag(
s) is formed at the cathode, and Pb
2+(
aq) is formed at the anode.
◦ Ag(
aq) is formed at the cathode and, Pb(
s) is formed at the anode.
◦ Pb(
s) is formed at the cathode, and Ag
+(
aq) is formed at the anode.
◦ Pb
2+(
aq) is formed at the cathode, and Cu(
s) is formed at the anode.
