Question

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?

A. At the equivalence point, the OH−concentration in the solution is 3.67×10−3 M.

B. The pH is less than 7 after adding 25 mL of NaOH solution.

C. The pH at the equivalence point is 7.00.

D. The HCl solution is less concentrated than the NaOH solution.

E. 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.
