the process is called the equivalence point of a titration. We can monitor the progress of acid-base titrations by two means. The first uses a pH meter, and the second uses an acid-base indicator. An indicator is a dye that has the particular property of changing color as a function of pH. Throughout the course of the lab, we utilized an acid-base titration of 10mL of an unknown solution (NaOH) as to determine its molarity. The titration process involved the repetitive dropping of .5 mL of .2M HCl into the unknown solution and the recording of the solution's pH as each drop was added.

9.2.1 Acid–Base Titration Curves. In the overview to this chapter we noted that a titration’s end point should coincide with its equivalence point. To understand the relationship between an acid–base titration’s end point and its equivalence point we must know how the pH changes during a titration. The titration graph for a strong acid + strong base would look like this: Notice the sharp slope around the equivalence point region - this is indicative of strong acid + strong base titrations. Note that the equivalence point pH is 7.0 - this is also what we would expect for this type of titration.
