Experiment # 4: Dissociation Constant Weak Acids
Introduction: The dissociation constants of weak monoprotic acids were determined with the aid of a buffer and pH meter.
Experiment: This experiment was performed according to the procedures as provided in the Chemistry 111B laboratory manual: Po, Henry and Senozan, N. "General Chemistry Experiments Chemistry 111B", 8th Ed., 2004 Hayden-McNeil Publishing, pp 80-88. To determine the dissociation constants of weak monoprotic acids (HX and HY), a buffer was needed to calibrate the pH meter. According to the manual, all four solutions to the…
