Acid-Base Pair

Definition of Acid-Base Pair from the PharmacyDictionary.in

Acid-Base Pair

An “Acid-Base Pair”, also known as a “Conjugate Pair”, refers to two substances that differ only by the presence of a proton. In an acid-base reaction, an acid donates a proton (H+) to a base, forming its conjugate base and the conjugate acid of the base. For example, in the reaction of acetic acid (CH3COOH) with water, acetic acid donates a proton to water, forming the acetate ion (CH3COO-) and hydronium ion (H3O+). Here, acetic acid and the acetate ion are an acid-base pair, and water and the hydronium ion are another acid-base pair. Understanding these pairs is crucial in the study of acid-base chemistry.
