A)katody kolejno: Bi, Cu, Ag
Anody: Zn, Al, Pb
B)
1) Zn| Zn2+ || Bi3+ | Bi
2) Al | Al3+ || Cu2+ | Cu
3) Pb | Pb2+ || Ag+ | Ag
C)
K: Bi3+ + 3e -> Bi
A: Zn-> Zn2+ + 2e
K: Cu2+ + 2e -> Cu
A: Al -> Al3+ + 3e
K: Ag+ + e -> Ag
A: Pb -> Pb2+ + 2e
D) SEM = Ek - Ea
SEM1 = 0,308 - (-0,762)=1,07V
SEM2= 0,342-(-1,676)=2,018V
SEM3 = 0,800- (-0,126)=0,926V
