A galvanic cell is set up with copper and lead electrodes
in contact with CuSO4(aq) and
Pb(NO3)2 (aq), respectively. If the
Pb2+ and Cu2+ concentrations are
each 1.0 M, what is the overall cell potential?
Pb2+(aq) + 2e- → Pb(s)
Eo = -0.22 V
Cu2+ (aq) + 2e- → Cu(s)
Eo = +0.34 V
A.
0.16 V
B.
0.76 V
C.
0.56 V
D.
0.36 V
