Question
Chapter 20, Problem 89IP
Interpretation Introduction
Interpretation: Among the given structures, the one that is not an intermediate in the given reaction has to be found.
Concept Introduction:
Intermediate: It is a molecular entity that will be formed from the reactants and reacts further with the reactant to give the desired products. It exists for a life time appreciably longer than a molecular vibration.
The given reaction is:
The following observations are made:
- It is clearly shown that the given reaction is a decomposition reaction since heat energy is involved. So ring opening had taken place in the product shown.
- The involvement of

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
How would you prepare 1 liter of a 50 mM Phosphate buffer at pH 7.5 beginning with K3PO4 and 1 M HCl or 1 M NaOH? Please help and show calculations. Thank you
