Conjugate base of hc9h7o4
WebIn the Brønsted–Lowry definition of acids and bases, a conjugate acid–base pair consists of two substances that differ only by the presence of a proton (H⁺). A conjugate acid is formed when a proton is added to a base, and a conjugate base is formed when a proton is removed from an acid. Created by Yuki Jung.

WebThe 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. Example 4 Identify the conjugate acid-base pairs in this equilibrium.
