Use the literature Ka value of the acetic acid, and the data below to answer these questions. Note: You will not use the experimental titration graphs to answer the questions that follow.
Group #1:
Buffer pH = 4.35
Group #2:
Buffer pH = 4.70
Group #3:
Buffer pH = 5.00
Group #4:
Buffer pH = 5.30
Use the Henderson-Hasselbalch equation, the buffer pH provided and the literature pKa value of acetic acid to perform the following:
a) calculate the ratios of [acetate]/[acetic acid] for each of the 4 groups buffer solutions above.
b) using the calculated ratios, which group solution will provide the best optimal buffer (Hint: what [acetate]/[acetic acid] ratio value is expected for an optimal buffer?)
c) explain your choice
