The structural formulas and relevant pKa values for the four components of an Excedrin tablet are shown. (The protonated form of the boxed group is shown.) A. Predict the migration order in capillary zone electrophoresis with a 20 mM borate run buffer at pH = 9.3. (Hint: First figure out charges on the species.) CA-] PH = pka + log CHAJ X 3.5 OH HO DK - 9.9 Acetaminophen Aspirin (acetyl salicylic acid) pK, = 3.0 OH OH K = 13.4 K, = 10.6 CH, salicylic acid caffeine B.
