Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

Feedback:
Note the presence of an acid and its
conjugate base in this buffer solution
to which acid has been added. To
solve this problem, you will need to
plug the appropriate pKa value into
the Henderson-Hasselbalch
equation. Recall the relationship
between pka and pKb for a given
conjugate acid-base pair.
