The Bronsted-Lowry acid-base definition ... an acid is a species having a tendency to lose a proton .... The use of the word species rather than substance of molecule implies that the terms acid and base are not restricted to uncharged molecules, but apply also to positively or negatively charged ions. This extension ... can be summarized by the equation [in which reactant A and the products B+H+ forms a reversible reaction] in which A and B together are a conjugate acid-base pair.  2, record 1, English, - conjugate%20acid%2Dbase%20pair

Théorie de Bronsted-Lowry. Couples acido-basiques. [...] Elle définit comme acide toute substance capable d’émettre des protons H+. [...] Il s’ensuit que dans un équilibre d’ionisation, on ne peut concevoir l'existence de l'acide sans celle de la base correspondante : on dit que la paire HA-A-ou B+-BOH forme un couple > acide-base.  3, record 1, French, - couple%20acide%2Dbase

The Brönsted-Lowry acid-base definition. ... an acid is a species having a tendency to lose a proton, and a base is a species having a tendency to gain a proton. The term proton means the species H+ (the nucleus of the hydrogen atom) rather than the actual hydrogen ions that occur in various solutions; the definition is thus independent of the solvent.  2, record 2, English, - Br%C3%B6nsted%2DLowry%20theory
