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). WebCH3COOH is a weak acid, while CH3COO- is a weak base (the Na+ is not important to the buffer, it can be considered a spectator ion). The pH of this buffer depends on the [CH3COOH] and the [CH3COO-].
