Chapter 17.3, Problem 17.7.1PE

An acid-base titration is performed: 250.0 mL of an unknown concentration of HCl (aq) is titrated to the equivalence point with 36.7 mL of a 0.1000 M aqueous solution of NaOH. Which of the following statements is not true of this titration?

1. The HCl solution is less concentrated than the NaOH solution.
2. The pH is less than 7 after adding 25 mL of NaOH solution.
3. The pH at the equivalence point is 7.00.
4. If an additional 1.00 mL of NaOH solution is added beyond the equivalence point, the pH of the solution is more than 7.00.
5. At the equivalence points, the OH- concentration in the solution is 3.67 × 10-3 M.
