question 12

Multiple Choice

Which of the statements below are true for the titration of Fe²⁺ with standard Ce⁴⁺?
I The indicator electrode potential before the addition of Ce⁴⁺ solution is calculated using the Fe³⁺ half-reaction after calculating the equilibrium concentrations of Fe³⁺ and Fe²⁺ in solution.
II Before the equivalence point,the indicator electrode potential is calculated using the Fe³⁺ half-reaction because only [Fe³⁺] and [Fe²⁺] are known.
III At the equivalence point,the indicator potential is the average of E^o for Fe³⁺ and Ce⁴⁺.
IV After the equivalence point,the indicator electrode potential is calculated using the Ce⁴⁺ half-reaction because only [Ce⁴⁺] and [Ce²⁺] are known.

• A)II and IV
• B)II,III,and IV
• C)I,III,and IV
• D)I,II,and IV
• E)I,II,III,and IV
