Transport of aspirin is expected to be faster in the ____. The speed of nonmediated absorption depends strongly on the polarity and charge of molecules. When p H is low (as it is in the _______), the aspirin molecule will be _______ and thus _______, due to _____ of H+ in the solution. The higher pH is, the _______ charged and polar will become the molecule, leading to the ____--- in the speed of absorption. One more evidence to this conclusion is that the pH in the _______ is much lower than pKa of aspirin comparing to the pH of the _______.
