Together, an acid with its conjugate base (such as HNO 3 and NO 3-) or a base with its conjugate acid (such as NH 3 and NH 4 +) is referred to as a conjugate acid-base pair. Lewis Acids and Bases In the Brnsted-Lowry definition of acids and bases, a base is defined as a compound that can accept a proton.

    Mar 22, 2011 · If you begin with a base and want to find the conjugate acid, just add an H+ to the formula. If you are given an acid and want to find the conjugate base, just remove an H+ from the formula. I'll show you a couple of each and you can do the rest.

    The two sets—NH 3 /NH 4 + and H 2 O/OH − —are called conjugate acid-base pairs. We say that NH 4 + is the conjugate acid of NH 3, OH − is the conjugate base of H 2 O, and so forth. Every Brønsted-Lowry acid-base reaction can be labelled with two conjugate acid-base pairs.
