|−|A '''conjugate acid''' is the [[molecule]] which results from a [[base]] accepting a [[proton]] (H<sup> +</sup> ). This molecule acts as an acid, with a strength inverse to the strength of the original base. An example conjugate base is an [[ ammonium]] ion (NH< sub> 4</ sub><sup> +</sup> ), which is the result of [[ammonia]] (NH<sub>3</sub>) reacting with an [[acid ]]. |+|

Consider the pair of molecules HX and X−. HX can react to form X−, and vice versa, through an acid-base reaction. Thus, HX is the conjugate acid of X− (and X− is the conjugate base of HX.)
HX acts as an acid, with a strength inversely proportional to the strength of its conjugate base.
