For groups (a) and (b) below, identify the best oxidizing and the best reducing agent in each group. You should have one oxidizing and one reducing agent (species) for a, and one of each for b. Assume the reaction as written, explain your reason if changing the direction.

a) Au 3+ (aq) + 3e- ? Au (s) Eo = 1.5V a) F (aq) + 2e-? 2F- (s) Eo = 2.87V

b) Zn2+ (aq) + 2e- ? Zn (s) Eo = -0.76 V b) Al3+ + 3e ? Al Eo = -1.66V

c) Which species from the above reactions would be most active (oxidize most easily)?

d) Write two complete reactions from the above list that happen spontaneously.

e) List all the species that react with Al and all the species that react with Zn.
