nounhʌɪˈdrəʊnɪəmhīˌdrōnēəm ˈīˌän

Chemistry

another term for hydroxonium ion
Example sentencesExamples
- Metals high on the activity series react more vigorously with oxidants including the halogens and the hydronium ion than those lower on the scale.
- Instead of floating free, hydrogen ions combine with water molecules to produce a positively charged hydronium ion.
- Some examples of positively charged electrophiles are the hydronium ion, nitronium ions, metal ions, and carbocations.
- A hydronium ion, however, disrupts this structure because it can accommodate a maximum of three hydrogen bonds.
- In response to that stress, the conjugate base reacts with the hydronium ion, producing more carbon dioxide which is removed from the system by increasing respiration.

Origin
