Consider the following half-reactions:
Cl2(g) + 2e- → 2Cl- (aq), Eo red = +1.359 V
I2 (s) + 2e- → 2I- (aq), Eo red = +0.536 V
Pb2+ (aq) + 2e- → Pb (s), Eo red = -0.126 V
V2+ (aq) + 2e- → V(s), Eo red = -1.18 V
From the list above:
(a) Which is the weakest oxidizing agent?
(b) Which is the strongest oxidizing agent?
(c) Which is the strongest reducing agent?
(d) Which is the weakest reducing agent?
(e) Will I-(aq) reduce V2+(aq) to V(s)?
(f) Will I2 (s) oxidize Cl- (aq) to Cl2(g)?
(g) Name the elements or ions that can be reduced by Pb(s).
