WebQuand un acide se dissocie dans l'eau en donnant des ions \text {H}^+ H+, ou protons, les ions \text {H}^+ H+ réagissent immédiatement avec l'eau pour former \text {H}_3\text {O}^+ H3O+. Ainsi, les chimistes parlent aussi bien de concentration en ions hydrogène (protons) ou en ions hydronium. Crédit Image : UC Davis Chemwiki, CC BY-NC-SA 3.0 US WebNot all ions are reactive (think of dissolving salt in water to give Na+ and Cl- ions) - it depends on the circumstances. H+ ions are more reactive than H3O+ ions, so when an acid dissociates in the water, the protons immediately latch on to water molecules to give H3O+ ions which are more stable than H+ ions.
