WebThe pH of a salt solution is determined by the relative strength of its conjugated acid-base pair. Salts can be acidic, neutral, or basic. Salts that form from a strong acid and a weak base are acid salts, like ammonium chloride (NH4Cl). Salts that form from a weak acid and a strong base are basic salts, like sodium bicarbonate (NaHCO3).

WebThat means that the ratio of conjugate acid: conjugate base is between 1:10 and 10:1, or at least ~10% of the molecules are in the minority form. So, you get a buffer if you PARTIALLY neutralize the acetic acid. For example, one mole of CH3COOH plus 0.4 moles NaOH will give 0.4 moles sodium acetate and 0.6 moles acetic acid leftover.
