Experiment 20: pH Titration Curves Jonathan Brate May 6, 2009 Wednesday Group 1 TA: Yosief Introduction: The purpose of Experiment 20 was to practice recording a series of titrations to find the titration curves. Much like in Experiment 18, this experiment demanded the use of HCl to lower the pH and NaOH to raise the pH of the unknown solutions. The theory of acid-base interactions, which is used in this experiment, was covered previously in the Chemistry 103 Lecture. A lab technique used was making pH vs. volume graphs. This was accomplished by the

use of pipets, biurets, a drop counter, a stir plate and magnetic stir rod, and the MeasureNet System. Procedure: For this experiment, the lab manual provided the procedure: Sprague, Alexander, Padolik & Steffel, Laboratory Experiments For First Year Chemistry, 7 th Edition. pp. 20-2 to 20- 5. In addition, the graphs weren’t uploaded to the MeasureNet website, but printed out as soon as the graph was found from the drop counter system. Results:
