Experiment #2:
Acid-Base Titration
Lab Description: Acid-Base Titration
Introduction
In this lab exercise we will evaluate the effectiveness of several indicators for the determination of the point of completion of a specific acid-base neutralization reaction. We will also determine the unknown concentration of the strong base NaOH by its reaction with a known amount of the weak acid, potassium acid phtalate (HKC8H4O4, abbreviated KHP). This will be accomplished using the titration …

…a bit. Ideally, the solution should have been added in very small increments. This would have allowed the end point determination to have been much more accurate.
These errors and inaccuracies are quite insignificant however and our experiment was successful in determining the NaOH titrant concentration and its pH of 13.03. We were also able to estimate the equivalence point of titration from the curve. We found the equivalence point occurs at a pH of approximatel 9.08.
