Which statements are TRUE for the titration of Fe²⁺ with Ce⁴⁺ to give Fe³⁺ and Ce³⁺?

1. Before the equivalence point, the indicator electrode potential is calculated using the Fe³⁺/Fe²⁺ half-reaction because both [Fe³⁺] and [Fe²⁺] are known.
2. At the equivalence point, the indicator electrode potential is the average of E^o for the Fe³⁺/Fe²⁺ half-reaction and the Ce⁴⁺/Ce³⁺ half-reaction.
3. After the equivalence point, the indicator electrode potential is calculated using the Ce⁴⁺/Ce³⁺ half-reaction because both [Ce⁴⁺] and [Ce³⁺] are known.
