8. All of the following are spontaneous reactions that proceed to the right. Standard reduction potentials at 259C are
provided for some half-cell reactions. Based on this information, rank the relative strengths of H+, Ag+ , Cd2+, Cu2+, and
Zn2+ as electron acceptors (oxidizing agents) at 25℃. (4%)
(A) Cu2+ > H+>Ag+ > Cd2+>Zn2+
(B) Ag+> Cu2+>H+> Cd2+>Zn2+
(C) Zn2+> Cd+>Ag+> Cu2+>H+
(D)Zn2+> Cd+> H+>Ag+ > Cu2+
(E) There is not enough information to deduce their relative oxidative strengths.
