BIOL 2083 Chapter : BIOL 2083 HW 1 Aspirin
Document Summary
Given that the fact that the ph of the stomach is 1-2 (very acidic). Now that we have seen that the aspirin is more basic than the stomach (1-2 > 3. 5), the h+ does not want to leave the molecule, and the proton donor properties of an acid will not allow for absorption. The high [h+] concentration in the stomach prevents the acids from dissociating further to produce more [h+] ions. Thus, in the stomach, the acids stay intact. With the intestines being more a more basic environment (ph 7), the conditions are more favorable for the disassociation of the [h+], because of the lower concentration of the ions.
