Volume of added base (mL)
A strong acid and a weak acid were titrated with the same strong base. Although the titration curves were constructed, they were not labeled. Assuming that both acids had a concentration of 1.0 M, what differences would allow each curve to be positively identified?
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
