Consider the following half-reactions: Half-reaction F2(g) + 2e- → 2F-(aq) E° = 2.870V Cd2+(aq) + 2e- → Cd(s) E° = -0.403V Al3+(aq) + 3e- → Al(s) E° = -1.660V (1) The weakest oxidizing agent is: enter formula (2) The strongest reducing agent is: (3) The strongest oxidizing agent is: (4) The weakest reducing agent is: (5) Will F-(aq) reduce Al3+(aq) to Al(s)? (6) Which species can be reduced by Cd(s)? If none, leave box blank.
