Problem

Which of the following is the strongest reducing agent?
                                                               E°
Sn2+(aq) + 2e- → Sn°                             -0.14
Cr3+(aq) + 3e- → Cr°                             -0.73
Sn4+(aq) + 4e- → Sn2+(aq)                     +0.15
Mn2+(aq)+ 2e- → Mn°                            -1.18
Cr2+(aq) + 2e- → Cr°                              -0.23

A) Sn2+(aq)

B) Mn2+(aq)

C) Sn4+(aq)

D) Cr2+(aq)

E) Mn°(aq)
