WebAug 30, 2024 · The pH of the buffer is 3.98. Can CH3COOH and CH3COONa make a buffer? A buffer solution resists (or buffers) a change in its pH. That is, we can add a small amount of an acid or base to a buffer solution and the pH will change very little. These are called Acid buffers e.g. CH3COOH + CH3COONa. (2) a weak base and its salt with a strong acid.
