Hydronium

In chemistry, hydronium is the common name for the aqueous cation , the type of oxonium ion produced by protonation of water. It is 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).

hydronium ion (hydronium)

(H₃O⁺). The H₃O⁺ ion, formed by capture of a hydrogen ion by a water molecule. A strong covalent bond is formed between the hydrogen ion and water oxygen; all hydrogen ions in aqueous solution are bound inside hydronium ions.
