Why Are Weak Acids Absorbed In The Stomach

Aspirin is a weak acid with a pKa of 3.5. It is absorbed into the blood through the cells lining the stomach and the small intestine.

A weak acid will be neutral until it dissociates into a negatively charged ion (anion) and a proton. While it hangs onto its proton, it is still neutral and thus lipid-soluble. In an alkaline environment, there are few protons, and the acid will tend to donate them, becoming ionised and losing its lipid-solubility.
