    Acetic Acid Buffers for pH Control - Stanford University

    acetic acid-acetate buffer follows the same trend to pH 6 and then flattens out towards the pH of the buffer (pH 4.8). The acetic acid buffer is effective but requires twice the volume (compared to H 2 SO 4) to get the pH down to less than 5. A buffer with lower prepared pH would have required less volume.

    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.
