Why is acetic acid and sodium acetate a good buffer? - Quora

Answer Wiki. What happens is, as the acid is used up, by alkaline or basic substances, more of the acetic acid hydrolyses and releases a hydrogen ion, which increases the acidity, to compensate. The reverse happens when an acid is added: the acetic acid does not hydrolyse so much and the hydrogen ions return to the acetate ion to re-form acetic acid.
