Question

1. Consider the following standard reduction potentials in acidsolution:
Cr3+ + 3e- ? Cr Eo = -0.74 V
Co2 + 2e- ? Co Eo = -0.28 V
MnO4 + 8H+ + 5e- ? Mn2+ + 4H2 Eo = +1.51 V
The strongest reducing agent listed above is.

2.Consider the following standard reduction potentials in acidsolution:
Eo(V) 3+ (aq) + 3e- ? Al(s) -1.66
Sn4+(aq) + 2e- ? Sn2+(aq) +0.14
I2(S) + 2e-? 2I-(aq) +0.53
Which is the weakest oxidizing agent in this list.
