Socalled “buffered aspirin” is not really a buffer, because it does not resist acids and bases. It is simply aspirin combined with a basic compound, such as magnesium carbonate or aluminum hydroxide, which neutralizes some stomach acid.

What does a weak acid do in a buffer?

If a strong base is added to a buffer, the weak acid will give up its H+ in order to transform the base (OH-) into water (H2O) and the conjugate base: HA + OH- → A- + H2O. Since the added OH- is consumed by this reaction, the pH will change only slightly.

What is the pH of buffered aspirin?
