Consider the following half reactions Half-reactionE° (V)
I2(s) + 2e- 2I-(aq) E 0.535V
Pb2+(aq) + 2e- Pb(s) E-0.126
VZn2+(aq) + 2e- Zn(s) E-0.763V
1. The strongest oxidizing agent
2.the weakest oxidizing
3 the weakest reducing
4 the strongest reducing
5 will I2(s) oxidize Zn(s) to Zn2+(aq) Yes/No
6 Which species can be oxidized by Pb2+(aq) if none leave box blank

Consider the following half-reactions:
Half-reaction
E° (V)
I2(s) + 2e -
→ 21(aq)
0.535V
Pb2*(aq) + 2e → Pb(s) |-0.126V
Zn*(aq) + 2e –→ Zn(s) -0.763VV
(1) The strongest oxidizing agent is: I,
enter formula
2+
(2) The weakest oxidizing agent is: Zn-
(3) The weakest reducing agent is: I
(4) The strongest reducing agent is:
(5) Will I2(s) oxidize Zn(s) to Zn²*(aq)? yes v
2+,
(6) Which species can be oxidized by Pb²*(aq)?
If none, leave box blank.
