Answer #1

Co^2+ (aq) + 2e^- ----------------> Co(s)           E0 = -0.29v

Fe^2+ (aq) + 2e^- -----------------> Fe(s)            E0 = -0.41v

Ni^2+ (aq) + 2e^- --------------> Ni(s)                    E0 = -0.25v

Al^3+ (aq) + 3e^-   -------------> Al(s)                   E0 = -1.66v >>>>>>reduction potential value is more . So it is strong reducing agent.

Al is best reducing agent

Choose the best reducing agent from the list below. A. Ni2+(aq) B. Ag(s) C.F2(g) D. Fe(s) I expected the answer to be A because the strongest reducing agent would be the most likely to be oxidized. Wouldn't a cation want to give up it's electrons, or be oxidized more than a metal solid or a highly electronegative halogen? The correct answer is D. Will someone please explain why this is?
