Web15 nov. 2024 · A water molecule (H20) plus a hydrogen ion (H+) becomes a hydronium ion (H3O+). The H+ ion is a lone proton with a powerful charge. It does not exist on its own in an aqueous solution because it is immediately attracted to the unshared or paired electron in the oxygen atom of H2O. The result is Hydronium (H3O+). This process is reversible. WebL'ion hydronium est le plus simple des ions oxonium ; sa formule chimique est H 3 O + ou H + (aq).
