What is the pKa of the hydronium, or oxonium, ion (H3O+)?
网页2014年4月9日 · The $\mathrm{p}K_\mathrm{a}$ of $\ce{H3O+}$ in ethanol is $0.3$ and $\mathrm{p}K_\mathrm{a}$ values are $1.0 \pm 0.3$ units lower in water than in ethanol, so the article suggests a $\mathrm{p}K_\mathrm{a}$ of $-0.7$ for $\ce{H3O+}$ in water, for the purpose of comparison to other acids.
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.
Water: What to use H3O+ or H+? - Chemistry Stack Exchange
网页2015年10月25日 · 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 to the electrons on water molecules and the symbol H3O+ is used to represent this transfer.
Solved Draw the major product of this reaction. Ignore - Chegg
网页To start the first problem, identify the site of the alkene (C=C) and determine how H 3 O + will protonate one of the carbons to form a more stable carbocation intermediate. Draw the major product of this reaction. Ignore inorganic byproducts. H3O+ Draw one of the two stereoisomers of the major product from this reaction.
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 ...
ions - Why doesn't H₄O²⁺ exist? - Chemistry Stack Exchange
网页2019年4月3日 · In this reaction $\ce{H3O^+}$ is the base, and $\ce{H^+}$ is the acid. Because solvents can strongly influence the acidity of basicity of dissolved compounds, and because inclusion of solvent makes calculations tremendously more complicated, we will restrict ourselves to the gas phase (hence $\ce{(g)}$ next to all the formulas).
Solved In an acidic solution, [H3O+] > [OH). True False A - Chegg
网页Our expert help has broken down your problem into an easy-to-learn solution you can count on. See Answer. Question: In an acidic solution, [H3O+] > [OH). True False A solution has [H3O+] = 4.0 x10-3 M. The [OH-] in this solution is O 2.5 x 10 -12 M none of these 4.0 x 1011 M. 1.0 x 10-14 M. 4.0 x 10-17 M.

Determine which ion, H3O+ or OH-, is in excess at the end of the ...
网页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. It happens because the $\ce{H+}$ is so, so positive (and therefore so reactive) that the water molecules, with its lone pairs (which are locally negatively charged), are willing to form ...
Is H+ (in an aqueous solution) = H3O+? - Chemistry Stack Exchange
网页2016年6月7日 · 3. When dealing with an aqueous solution, you are correct that the HX+ H X + ion is equivalent to HX3OX+ H X 3 O X + for all intents and purposes. Due to the abundance of water in solution, molecules of HX2O H X 2 O will readily pick up the hydrogen ions, meaning that most of the HX+ H X + in an aqueous solution is actually of the form …
