It is possible to make a buffer that functions well near pH7 using citric acid, which contains only carboxylate groups. Explain.
We usually say that a perfect buffer has its pH equal to its pKa. Give an example of a situation in which it would be advantageous to have a buffer with a pH 0.5 unit higher than its pKa.
Based on the information in Table 3.2, is there any amino acid that could serve as a buffer at pH 8? If so, which one?
