Question 1

Consider the following standard reduction potentials in acid solution:
         
 
E°(V)
Al3+ + 3e–→ Al(s)
–1.66
Sn4+ + 2e–→ Sn2+
+0.14
I2(s) + 2e–→ 2I– (aq)
+0.53

Which is the weakest oxidizing agent in this list?

◦ Al3+(aq)
◦ Al(s)
◦ I–(aq)
◦ I2(s)
◦ Sn4+(aq)

Question 2

Consider the following standard reduction potentials in acid solution:
Cr3+ + 3e–→ Cr
E° = –0.74 V
Co2+ + 2e–→  Co
E° = –0.28 V
MnO4–  + 8H+ + 5e–→ Mn2+ + 4H2O
E° = +1.51 V

The weakest reducing agent listed above is

◦ Cr3+.
◦ Cr.
◦ Mn2+.
◦ Co.
◦ MnO4–.
