Definition of hydroxonium ion in English:

hydroxonium ion

nounˌhʌɪdrɒkˈsəʊnɪəmˌhīdräkˌsōnēəm ˈīˌän

Chemistry

The ion H₃O⁺, consisting of a protonated water molecule and present in all aqueous acids.
〔化〕水化氢离子
Example sentencesExamples
- One assumes that it is the hydroxonium ions but is this necessarily the case?
- The trajectories of movement of the hydroxyl and hydroxonium ions are cycloids.
- When acetic acid dissociates in water it loses hydrogen to form the hydroxonium ion, H 3 O +, and the acetate ion.
- Further down this page, we shall calculate the concentration of hydroxonium ions present in pure water.
- The complex ion is deprotonated, causing the solution to be acidic from the formation of hydroxonium ions H 3 O +.

Origin

1920s: hydroxonium from hydro- (relating to hydrogen) + oxy-² + the suffix -onium (from ammonium).
