Diketahui data :
E0 Mg 2+/Mg = - 2,37 Volt
E0 Cu 2+/Cu = + 0,34 Volt
E0 Ag +/Ag = + 0,80 Volt
E0 Fe 2+/Fe = - 0,44 Volt
E0 Pb 2+/Pb = - 0,13 Volt
Sel Volta yang menghasilkan listrik dengan potensial sel standar terbesar adalah ....
Mg + Pb2+→ Mg2+ + Pb
Mg + 2 Ag+ → Mg2+ + 2 Ag
Mg + Cu2+→ Mg2+ + Cu
Pb + Cu2+ → Pb2+ + Cu
Fe + 2 Ag + → Fe2+ + 2 Ag
