A solution of a weak acid is titrated with a standard solution of a strong
base. The progress of the titration is followed with a pH meter. Which of
the following observations best describes what would occur?
Initially the pH of the solution increases slowly, and then it increases much
more rapidly, before increasing slowly again
At the equivalence point, the pH is 7
The pH of the solution gradually decreases throughout the experiment
After the equivalence point, the pH becomes constant because this is the
buffer
