It is the positive ion present when an Arrhenius acid is dissolved in water, as Arrhenius acid molecules in solution give up a proton to the surrounding water molecules.
IUPAC ID: Hydronium ion
Formula: H3O+
Molar mass: 19.0232 g/mol
ChemSpider ID: 109935
Acidity (pKa): -1.74 or 0 (ambiguous, see text)
Conjugate base: Water
Explanation:
It's chemical formula is H3O+. It can also be formed by the combination of a H+ ion with an H2O molecule. The hydronium ion has a trigonal pyramidal geometry and is composed of three hydrogen atoms and one oxygen atom. There is a lone pair of electrons on the oxygen giving it this shape.
