WebApr 11, 2024 · Calculate the degree of ionization of morphine pKa 8.0 in a solution with a pH of 2.2. Predict how the degree of ionization could affect the ease of absorption of morphine in (a) the stomach and (b) the intestine when the pH of the stomach fluid is 2.0 and the pH of the intestinal fluid is 6. WebThis is crucial to the action and detection of the compound as a drug, pollutant, or other active chemical agent. In many cases it is desirable to predict pKa values prior to synthesizing a compound, and enough is now known about the salient features that influence a molecule’s acidity to make these predictions.
