Notice that the conjugate base of a weak acid is also a strong base. Start studying Conjugate acid &base. The primary difference between acetate and acetic acid can be said that acetate is a neutral compound, whereas acetate is an anion that carries a net negative electric charge. For example, the acetate ion has a small tendency to accept a hydrogen ion from water to form acetic acid and the hydroxide ion. Sodium acetate also contains an acetate ion. . What is the concentration of its conjugate base H2PO 4 at pH 3.21 in 2.37 mol/L phosphoric acid? Acetic acid's conjugate base is sodium acetate. Acetone is a flammable substance with a fruity smell.
