An ion of the type R3O+, in which R indicates hydrogen or an organic group, especially the ion H3O+, which is formed when acids dissociate in water. 5, record 1, English, - oxonium%20ion

Most of the time, the hydronium ion, symbol H3O+, is called hydrogen ion, symbol H[plus], even if the notion described by this term (hydrogen ion) represents not an hydrogen ion but "a proton (hydrogen ion) combined with a molecule of water." 6, record 1, English, - oxonium%20ion

L'ion hydrogène H[plus], ou proton, est le noyau de l'atome d'hydrogène. Il ne semble pas que le proton puisse exister à l'état libre dans un solvant comme l'eau. Il s'associe en effet à une molécule d'eau, qui joue le rôle de base (accepteur de protons), pour former l'ion hydronium H3O+, ou ion hydrogène hydraté [...]. L'eau peut jouer aussi le rôle d'acide (donneur de protons) [...] 4, record 1, French, - ion%20oxonium
Record number: 1, Textual support number: 1 OBS
L'ion hydronium, de formule H3O+, est presque toujours appelé ion hydrogène, symbole H[plus]; l'ion d'hydrogène, n'existant pas à l'état libre dans l'eau, s'associe à une molécule d'eau pour former l'ion hydronium; cet ion hydronium par commodité est appelé ion hydrogène. 5, record 1, French, - ion%20oxonium
Record number: 1, Textual support number: 2 OBS
Le proton en solution aqueuse peut donner lieu à plusieurs écritures : - H[exposant]+(aq); cette écriture conventionnelle, simple et cohérente avec celle utilisée pour les autres ions, facilite l'écriture de nombreuses équations chimiques. - H3O+ (l'IUPAC recommande l'appellation oxonium). L'écriture H3O+(aq) n'est pas nécessaire. 6, record 1, French, - ion%20oxonium
