Cоnsider the vоltаic cell diаgrаm: Al (s) | Al3⁺(aq) || Fe2⁺ (aq) | Fe (s) What is the standard cell pоtential, E°cell, (in V) for this voltaic cell? Hint: Refer to the table of standard reduction potentials provided. Half Reaction E° red (V) Ag+ (aq) + e– → Ag (s) +0.80 Fe3+ (aq) + e– → Fe2+ (aq) +0.77 Cu2+ (aq) + 2 e– → Cu (s) +0.34 Sn4+ (aq) + 2 e– → Sn2+ (aq) +0.15 2H+ (aq) + 2 e– → H2 (g) 0.00 Pb2+ (aq) + 2 e – → Pb (s) –0.13 Sn2+ (aq) + 2 e– → Sn (s) –0.14 Ni2+ (aq) + 2 e – → Ni (s) –0.28 Cd2+ (aq) + 2 e – → Cd (s) –0.40 Fe2+ (aq) + 2 e – → Fe (s) –0.44 Cr3+ (aq) + 3 e– → Cr (s) –0.74 Zn2+ (aq) + 2 e – → Zn (s) –0.76 Al3+ (aq) + 3 e– → Al (s) –1.66
