hydronium
Definition
- In chemistry, hydronium (hydroxonium in traditional British English) is the common name for the aqueous cation H₃O⁺, the type of oxonium ion produced by protonation of water. It is often viewed as the positive ion present when an Arrhenius acid is dissolved in water, as Arrhenius acid molecules in solution give up a proton (a positive hydrogen ion, H⁺) to the surrounding water molecules (H₂O). In fact, acids must be surrounded by more than a single water molecule in order to ionize, yielding aqueous H⁺ and conjugate base.
