Question 1

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 strongest reducing agent listed above is

◦ Cr3+.
◦ Cr.
◦ Mn2+.
◦ Co.
◦ MnO4–.

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 strongest oxidizing agent listed above is

◦ Cr3+.
◦ Cr.
◦ Mn2+.
◦ Co2+.
◦ MnO4–.
