  1. What is the pKa of the hydronium, or oxonium, ion (H3O+)?

    Apr 9, 2014 · There is the problem of having 55.56 molar hydronium re its counterion being included. Consider water azeotropes of strong acids not by wt-% but by mole ratio. Is there anything …

  2. acid base - Is it the hydronium ions or the H+ ions that makes the ...

    Jan 22, 2025 · Hydronium is a simplification but it is accurate that pure protons don't exist. Furthermore, hydrogen ions freely move - through Grotthuss Mechanism, they bind to a water to form hydronium, …

  3. Can pure hydronium exist? - Chemistry Stack Exchange

    Oct 18, 2023 · Can pure hydronium exist? If not, why not? It seems to me (and I am no chemistry expert) like pure hydronium should have the theoretical maximum acidity or minimum pH that a …

  4. enthalpy of formation of hydronium - Chemistry Stack Exchange

    Nov 30, 2021 · Since aqueous hydronium and aqueous hydrogen ions are the same, we expect these two reactions to have the same reaction enthalpy. And since aqueous hydrogen ions have an …

  5. Water: What to use H3O+ or H+? - Chemistry Stack Exchange

    Oct 25, 2015 · In all cases, acids yield protons ( or hydronium ions H3O+) and bases yield OH- (hydroxide) ions in aqueous solutions. The H3O+ ion is considered to be the same as the H+ ion as it …

  6. How to calculate Ka for hydronium and Kb for hydroxide?

    For hydronium: $$\ce {K_a = \frac { [H^+] [H_2O]} { [H_3O^+]}}$$ and the source of the proton in question is not likely water (normally a stronger mineral acid). If you put the water on both sides of …

  7. inorganic chemistry - What are the dissociation constants of …

    Jun 8, 2023 · The question was marked duplicate to What is the pKa of the hydronium, or oxonium, ion (H3O+)?, and the answer disregarded auto-protonation of water as a thermodynamic process while …

  8. Is hydronium an electrophile, nucleophile, both or neither?

    Mar 22, 2018 · Below is an arrow-pushing mechanism depicting the deprotonation of hydronium. *Note that the oxygen of α-Methylbenzyl alcohol is acting as the nucleophile to attack a hydrogen atom of …

  9. Physical state of hydronium - Chemistry Stack Exchange

    Dec 1, 2012 · I am doing my chemistry homework and I am supposed to write the products when strong acids react with water, but I am unsure of the physical state for hydronium ions. Should it be liquid (l) …

  10. Solid salts of hydronium ion - Chemistry Stack Exchange

    Feb 20, 2020 · There is a section in this entitled, "Solid hydronium salts." It says that any acid with an ionization constant of 10^9 or higher may form stable hydronium ion salts. Examples they give …
