At the equivalence point, the pH = 7.00 for strong acid-strong base titrations. However, in Lab 10. Outline. Purpose. Potentiometric. Titrations. Proticity. Equivalence. pK. a. Vinegar Titration. Calculations. Waste. Following Lab Reminder. pH Probe Calibration. Purpose. Students will use a pH probe to perform potentiometric titrations to determine the mass percent of acetic acid in vinegar and the pKa of acetic acid. . A Physician’s perspective. Navin K Jain, MD. CONFLICT OF INTEREST. None to disclose. OBJECTIVES. Learn PAP titration protocols. Learn current practices in PAP titration. Understand a “good titration. Titration. Acid–Base Titration. The concentration of a weak acid or a weak base in water is difficult – if not impossible – to measure directly.. But we can calculate the concentration from the results of titration.. S. aud .
