Given that E°K+ /K = -2.93 V;
E°Fe2+/Fe = -0.44V; E°Zn2+/Zn = -0.76V;
E°Cu+2/Cu = 0.34V
Based on this data, which of the following is the strongest reducing agent?
(a) Cu(s)
(b) K+ (aq)
(c) Zn2+ (aq)
(d) Fe(s)

(d) Fe(s)
Explanation:
K+ (aq) and Zn2+ (aq) can not lose electron(s). Fe has greater tendency to lose electrons than Cu.
[E°Fe2+/Fe = -0.44V > E°Cu+2/Cu = 0.34V]
