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.
