vanadium pentoxide
TechnicalScientific/Industrial
Definition
Meaning
A chemical compound with the formula V₂O₅, used as an industrial catalyst and in ceramics.
The most common oxide of vanadium, appearing as a yellow to red crystalline powder with important applications in sulfuric acid production and as a pigment.
Linguistics
Semantic Notes
Always refers specifically to V₂O₅; other vanadium oxides have different names (e.g., vanadium dioxide).

Examples
By Part of Speech
verb
British English
- The process involves vanadium pentoxide catalysing the reaction.
American English
- The new method uses vanadium pentoxide to catalyze the oxidation.
adverb
British English
- The sample reacted vanadium pentoxide-catalytically.
American English
- The oxidation proceeds vanadium pentoxide-efficiently.
adjective
British English
- The vanadium pentoxide catalyst bed requires careful monitoring.
American English

Examples
By CEFR Level
- Vanadium pentoxide is a chemical.
- The factory uses vanadium pentoxide to make other chemicals.
- As a catalyst, vanadium pentoxide accelerates the production of sulfuric acid without being consumed.
- The efficacy of the vanadium pentoxide catalyst is contingent upon its specific surface area and the reaction temperature.
Learning
Memory Aids
Mnemonic
Think: VAN (vehicle) + ADIUM (adding) PENT (five) OXIDE (oxygen) → a compound adding five oxygen atoms to vanadium.
Conceptual Metaphor
An industrial workhorse (due to its key catalytic role).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Direct translation yields 'пентаоксид ванадия', which is correct but less common than 'оксид ванадия(V)' or 'V₂O₅' in technical contexts.
Common Mistakes
- Misspelling as 'vanadium pentoxide' (incorrect capitalization)
- Confusing it with other vanadium oxides.
- Using 'vanadium oxide' ambiguously instead of the precise 'vanadium pentoxide'.

FAQ
Frequently Asked Questions
Yes, it is toxic if inhaled or ingested and is an irritant to skin and eyes, requiring proper safety handling.
Yes, it occurs as the rare mineral shcherbinaite, but is typically produced industrially.
Because the vanadium atom is in the +5 oxidation state, combined with oxygen in a 2:5 ratio (V₂O₅).
It is typically a yellow, orange, or reddish-brown powder, depending on purity and particle size.
