Its conjugate acid is H 2 CO 3, and its conjugate base is CO 3 2–. The use of conjugate acid-base pairs allows us to make a very simple statement about relative strengths of acids and bases. The stronger an acid, the weaker its conjugate base , and, conversely, the stronger a base, the weaker its conjugate acid. Drift email bots
