Aspirin is а weаk аcid with a p K a оf 3.5 (the iоnizable H is shоwn in red): Aspirin is absorbed into the blood through the cells lining the stomach and the small intestine. Absorption requires passage through the plasma membrane. The polarity of the molecule determines the absorption rate: charged and highly polar molecules pass slowly, whereas neutral hydrophobic molecules pass rapidly. The pH of the stomach contents is about 1.5, and the pH of the contents of the small intestine is about 6. Based on this information, is more aspirin absorbed into the bloodstream from the stomach or from the small intestine?
