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

    Oct 25, 2015 · The H3O+ ion is considered to be the same as the H+ ion as it is the H+ ion joined to a water molecule. The proton cannot exist in aqueous solution, due to its positive charge it is attracted …

  2. 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 …

  3. Why does water dissociate to H3O+ and OH- rather than H+ and OH-?

    Why does water dissociate to $\ce {H3O+ + OH-}$ instead of $\ce {H+ + OH-}$? This question came to surface when I was learning about acids and bases, and learned this definition:

  4. Which is a stronger acid: H3O+ or HCl? - Chemistry Stack Exchange

    Jul 15, 2016 · I know as a fact that HCl is a stronger acid than H3O+, but I want to know the reason behind it. The definition of an acid is a substance which dissociates to give H3O+ ions. In that case …

  5. How to calculate the concentration H3O+ in a solution with pH=6.99?

    Jan 24, 2016 · 1 The pH is close to 7. So the hydronium ion concentration of water can't be neglected. [H3O+fro water + H3O+ from acid] [OH-]=10^-14 Please note that H2O dissociates partially to form …

  6. Determine which ion, H3O+ or OH-, is in excess at the end of the ...

    0 H3O+ is just the combination of a a $\ce {H+}$ ion, which we know to be released from the dissociation of an acid in an aqueous solution, with a water molecule.

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

    5 This question already has answers here: What is the pKa of the hydronium, or oxonium, ion (H3O+)? (3 answers)

  8. 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) …

  9. Is H+ (in an aqueous solution) = H3O+? - Chemistry Stack Exchange

    Jun 7, 2016 · 3 When dealing with an aqueous solution, you are correct that the $\ce {H+}$ ion is equivalent to $\ce {H3O+}$ for all intents and purposes. Due to the abundance of water in solution, …

  10. Balancing redox equations in acidic media: to use H+ or H3O+?

    May 30, 2014 · Yes, $\ce {H3O^+}$ is a closer representation of reality and so if "that" is important to you, then you would use $\ce {H3O^+}$. However, I could imagine someone else arguing that …
