The concentration of acetylcholine (a neurotransmitter) in a sample can be determined from the pH changes that accompany
its hydrolysis. When the sample is incubated with the enzyme acetylcholinesterase, acetylcholine is converted to choline
and acetic acid, which dissociates to yield acetate and a hydrogen ion.

In a typical analysis, 11 mL of an aqueous solution containing an unknown amount of acetylcholine had a pH of 7.70.
When incubated with acetylcholinesterase, the pH of the solution decreased to 6.89. Assuming there was no buffer in the
assay mixture, determine the number of moles of acetylcholine in the 11 mL sample.
Describe buffer solutions in terms of acid-base equilibria. Give an example. How can you overwhelm buffer capacity?
