xenic acid
Very lowTechnical/Scientific
Definition
Meaning
A weak, unstable acid with the chemical formula H₂XeO₄, formed by the dissolution of xenon trioxide in water. A rare compound of the noble gas xenon in its highest oxidation state (+6).
Used exclusively in specialized chemistry, particularly inorganic and noble gas chemistry, to refer to this specific compound. The term may appear in discussions of xenon chemistry, the reactivity of noble gases, and oxidation-state studies.
Linguistics
Semantic Notes
The term is a hypernym for the specific compound. It is not a category of acids but refers to one specific chemical entity. 'Xenate' refers to its salts.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'ксеноновая кислота' (which is correct but very rare). The main trap is assuming it is a common term; it is highly specialised.
Common Mistakes
- Mispronouncing as 'zen-ik' (US) vs. 'zee-nik' (UK). Misspelling as 'xenon acid'. Using it as a general term instead of a specific compound name.

FAQ
Frequently Asked Questions
No, it is a weak acid, but it is a very strong oxidizing agent.
No, it is not commercially available due to its instability and highly specialised nature. It is prepared in situ for research purposes.
Salts of xenic acid are called xenates (e.g., sodium xenate, Na₂XeO₄).
Because xenon chemistry itself is a niche field, and xenic acid is just one specific, unstable compound within it.
