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 …showed first 75 words of 823 total…

…showed last 75 words of 823 total…Ka value will be given then the other solutions which had base in the solution. Also, since the solutions of the experiment were prepared first before calibrating the pH meter, the group received a better pH reading because the pH of the solutions were measured one after the other.
Conclusion: In the experiment, it was seen that the dissociation of weak monoprotic acids were constant for HX and for HY given from the Ka values.
