Which of the following species is the strongest oxidizing agent under standard state conditions? a. Ag+(aq) b. H2(g) c. H+(aq) d. Cl2(g) e. Al3+(aq) An oxidizing agent is a substance that gains electrons in a redox chemical reaction. I think Al3+ has a very high electron affinity and should pull electrons to it in a chemical reaction. Is Al3+ the best choice for this problem?
