What is the pKa of the hydronium, or oxonium, ion (H3O+)?
网页2014年4月9日 · $\begingroup$ 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. Consider water azeotropes of strong acids not by wt-% but by mole ratio.
Physical state of hydronium - Chemistry Stack Exchange
网页2012年12月1日 · 7. This is a bit touchy. The problem is that a bare proton, HX+ H X +, won't exist in water. It attracts electrons too strongly. Once this was recognized, chemists started to write the bare proton as being bound to a water molecule, thus HX3OX+ H X 3 O X +. However, studies also showed that water molecules are typically linked together in ...
How to calculate Ka for hydronium and Kb for hydroxide?
网页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 the equation you are describing another …
enthalpy of formation of hydronium - Chemistry Stack Exchange
网页2021年11月30日 · 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 enthalpy of formation of 0 (by definition), the only way the two reactions will have the same reaction enthalpy is if hydronium and water have the same …
Solid salts of hydronium ion - Chemistry Stack Exchange
网页2020年2月20日 · It says that any acid with an ionization constant of 10^9 or higher may form stable hydronium ion salts. Examples they give include hydronium perchlorate and carborane-based hydronium ion salts. Share. Cite. Improve this answer. answered Jun 22, 2014 at 21:09. ron. 85.2k 14 232 323.
Is hydronium an electrophile, nucleophile, both or neither?
网页2018年3月22日 · As a result, one of the hydrogen atoms of hydronium is quite easy to strip off, giving it its strong acidity (pKa~ -1.74). Since no other parts of hydronium react with other species, the only reactive component is the hydrogen atom, which serves as an electrophile and gives hydronium its categorization as an electrophile.
Water: What to use H3O+ or H+? - Chemistry Stack Exchange
网页2015年10月25日 · 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 is the H+ ion joined to a water molecule.
Can pure hydronium exist? - Chemistry Stack Exchange
网页2023年10月18日 · OTOH, hydronium balanced with counter anion of a strong acid, dissolved in water, is a common molecular entity chemists works with. There can be easily $\pu{200 g/L}$ of hydronium ions. Note that crystalline monohydrate of some very strong acids is de facto a hydronium salt $\ce{[H3O+][A-]}$.
Which is a stronger acid: H3O+ or HCl? - Chemistry Stack Exchange
网页2. 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 H3O+ should be the strongest acid available because it does not even need to dissociate it give itself!! acid-base. equilibrium. Share.
