Question
Quinine (C20 H24 N2O2) is the most important alkaloid derived from cinchona bark. It is used as an antimalarial drug. For quinine, pKb, = 5.1 and pK, = 9.7 (pK, = - log Kp). Only 1 g quinine will dissolve in 1930.0 mL of solution.
Calculate the pH of a saturated aqueous solution of quinine. Consider only the reaction
Q+ H20 = QH+ + OH°
described by pK,, where Q = quinine.
pH =
