22. Fe²⁺ is titrated with Ce⁴⁺ to form Fe³⁺ and Ce³⁺. Which statements are TRUE of the potential at the equivalence point of this titration?
(A) The potential is equal to the sum of the standard reduction potentials of the two half-reactions minus the potential of the reference electrode.
(B) The potential is cqual to the sum of the standard reduction potentials of the two half-reactions.
(C) The potential is equal to the average of the standard reduction potentials of the two half-reactions minus the potential of the reference electrode.
(D) The potential is equal to the average of the standard reduction potentials of the two half-reactions.
(E) It lies at the mid-point of the redox titration curve.
