Problem

Which of the following is the weakest oxidizing agent?

                                                                     E°
Sn2+ + 2e- → Sn°                                      -0.14
Cr3+ + 3e- → Cr°                                       -0.73
Sn4+ + 4e- → Sn2+                                    +0.15
Mn2+ + 2e- → Mn°                                     -1.18
Cr2+ + 2e- → Cr°                                       -0.23

A) Sn2+(aq)

B) Mn2+(aq)

C) Sn4+(aq)

D) Cr2+(aq)

E) Cr3+(aq)
