Oxonium ion - Wikipedia
网页Hydronium is one of a series of oxonium ions with the formula R n H 3−n O +. Oxygen is usually pyramidal with an sp 3 hybridization. Those with n = 1 are called primary oxonium ions, an example being protonated alcohol (e.g. methanol).

Hydronium ion - American Chemical Society
网页2020年9月28日 · What molecule am I? All acidic aqueous solutions contain protonated water, known commonly as the hydronium ion (H 3 O +). Brønsted acids release one or more of their protons (hydrogen ions), which combine with water molecules. Lewis acids extract one or more hydroxyl ions from water to release hydrogen ions, which, again, form hydronium ions.
What is the pKa of the hydronium, or oxonium, ion (H3O+)?
网页2014年4月9日 · The controversy surrounding the pKa of hydronium mostly arises from the definition of Ka or lack thereof. There is no IUPAC definition of pKa or Ka. The closest IUPAC defined term is the standard equilibrium constant, which can be denoted as K …
