Problem Details

Calculate the standard cell potential of a Al/Al 3+ | Cd/Cd2+ voltaic cell. 

Al3+ (aq) + 3e → Al(s)      E ̊red = –1.66 V

Cd2+ (aq) + 2e → Cd(s)    E ̊red = –0.403V

a) –2.11 V; nonspontaneous

b) 2.11 V; spontaneous

c) 1.26 V; spontaneous

d) –1.26 V; nonspontaneous

e) 1.257 V; non‐spontaneous
