tungstic acid
C2Technical/Scientific
Definition
Meaning
A compound of tungsten, specifically the yellow tungsten trioxide hydrate (H₂WO₄) or a derivative, used primarily in chemical processes and industry.
Any acid containing tungsten, especially in its highest oxidation state (+6), notable for forming heteropoly acids and acting as a catalyst or a chemical intermediate.
Linguistics
Semantic Notes
Refers strictly to chemical compounds containing tungsten and oxygen in acidic form; not encountered outside specialised contexts.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage between UK and US English. The chemical nomenclature is internationally standardised.
Connotations
Solely technical, with no additional cultural or regional connotations.
Frequency
Extremely rare in general language; frequency is identical and confined to chemistry, materials science, and industrial contexts in both varieties.

Examples
By Part of Speech
adjective
British English
- The tungstic acid solution was carefully filtered.
American English
- A tungstic acid catalyst was employed in the reaction.
Examples
By CEFR Level
- Tungstic acid is a chemical.
- Scientists sometimes use tungstic acid in experiments.
- The yellow precipitate formed was identified as tungstic acid.

Learning
Memory Aids
Mnemonic
Think: TUNGSten makes an ICky ACID → TUNGSTIC ACID. It’s the acidic form of tungsten.
Conceptual Metaphor
None in common usage. Technically viewed as a 'building block' or 'precursor' in chemical synthesis.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation as 'вольфрамовая кислота' unless the specific compound H₂WO₄ is intended, as the Russian term can sometimes refer more broadly to tungstates.
Common Mistakes
- Confusing 'tungstic' with 'tungsten' (the element).
- Misspelling as 'tungstenic acid'.
- Using it as a countable noun (e.g., 'a tungstic acid') instead of an uncountable mass noun.

FAQ
Frequently Asked Questions
As a chemical reagent, it should be handled with standard laboratory safety precautions, but its specific hazards depend on concentration and form.
It is primarily used as a precursor to other tungsten compounds, in catalysts, and in the production of tungsten metal and ceramics.
No, it is a synthetic compound produced through chemical processing of tungsten ores.
It typically forms a bright yellow powder or crystalline solid.
