Line 1:
Line 1: − A '''conjugate base''' is the negatively charged [[ion]] which results from an acid donating a [[proton]] (H<sup>+</sup>). This ion acts as a [[base]], with a strength inverse to the strength of the original acid. An example conjugate base is a [[nitrate]] ion (NO<sub>3</sub><sup>-</sup>), which is formed when [[nitric acid]] (HNO<sub>3</sub>) gives up its proton.+ − + + + − +

When a molecule donates a proton, it is called the '''conjugate base''' of the original molecule. For example, NH<sub>3</sub> is the conjugate base of NH<sub>4</sub><sup>+</sup>. NH<sub>4</sub><sup>+</sup> and NH<sub>3</sub> are a conjugate acid-base pair. One can be transformed into the other by undergoing a simple [[acid-base reaction]].

The conjugate acid acts as an acid, with a strength inversely proportional to the strength of its conjugate base. For example, since NH<sub>3</sub> is a weak base, NH<sub>4</sub><sup>+</sup> is a fairly strong acid.
