Acid-dissociation constants of two acids are listed in the table above. A 20. mL sample of a 0.10 M solution of each acid is titrated to the equivalence point with 20. mL of 0.10 M NaOH. Which of the following is a true statement about the pH of the solutions at the equivalence point?
(A) Solution I has a higher pH at the equivalence point because CH_3CO_2H is the stronger acid.
(B) Solution 1 has a higher pH at the equivalence point because CH_3CO_2H has the stronger conjugate base.
(C) Solution 1 has a lower pH at the equivalence point because CH_3CO_2H is the stronger acid.
