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^–.
