Question

Questions 26-28 refer to the following information.

The structure of haloacetic acids, XCH2COOH (where X is either F, Cl, Br, or I ), is shown below.

[VISUAL]

A student titrates 10.0 mL samples of 1.0 M solutions of each of the haloacetic acids with a standard solution of NaOH. Which of the following statements correctly predicts the volume of NaOH(aq) needed to reach the equivalence point?

A.

Fluoroacetic acid will need the smallest volume of NaOH(aq) to reach the equivalence point.

B.

Iodoacetic acid will need the smallest volume of NaOH(aq) to reach the equivalence point.

C.

All of the acids will need the same volume of NaOH(aq) to reach the equivalence point.

✓ Correct
D.

All of the haloacetic acids are weak; therefore none will reach an equivalence point.
