iodic acid
C2Highly technical/Formal
Definition
Meaning
A white crystalline inorganic acid with the chemical formula HIO₃, containing iodine in a +5 oxidation state.
A moderately strong acid used as a reagent in analytical chemistry and organic synthesis, capable of oxidizing various compounds.
Linguistics
Semantic Notes
This is a highly specific chemical term. It refers exclusively to the compound HIO₃. It is not to be confused with the more common 'hydroiodic acid' (HI) or iodine itself.
Dialectal Variation

Differences
No significant lexical differences. Both varieties use the same term identically in technical contexts.
Connotations
No connotative differences. Purely denotative chemical term.
Frequency
Identical, extremely low frequency in general language but standard within chemistry.

Examples
By Part of Speech
verb
British English
- The compound was iodicised to form the salt.
- They attempted to iodicise the substrate.
American English
- The compound was iodinated using a different pathway.
- They oxidized the material to an iodate.
adjective
British English
- The iodic acid solution was carefully titrated.
- An iodic acid derivative was synthesised.

Examples
By CEFR Level
- Iodic acid is a chemical used in some laboratories.
- The formula for iodic acid is HIO₃.
- In the redox titration, the iodic acid acted as a strong oxidising agent.
- The crystalline structure of iodic acid was determined by X-ray diffraction.
Learning
Memory Aids
Mnemonic
Think 'I OWE an ACID' – the 'IO' from iodine and 'DIC' from its name combine to make 'IODIC' acid.
Conceptual Metaphor
An oxidising agent is a weapon (e.g., 'Iodic acid attacks the double bond').
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'йодистая кислота' (HIO₂, iodous acid). The correct translation is 'йодноватая кислота'.
Common Mistakes
- Pronouncing it as 'eye-oh-dick' /aɪˈoʊ.dɪk/ instead of 'eye-od-ic' /aɪˈɒd.ɪk/ or /aɪˈɑː.dɪk/.
- Confusing it with 'iodine' or 'iodide'.

FAQ
Frequently Asked Questions
Yes, as a strong oxidising agent and corrosive acid, it can cause severe burns and react violently with combustible materials. It requires careful handling in a controlled laboratory setting.
Iodic acid (HIO₃) contains iodine in a +5 oxidation state and is an oxidising acid. Hydroiodic acid (HI) contains iodine in a -1 oxidation state and is a strong reducing acid.
Extremely unlikely. It is a specialised laboratory chemical not used in consumer products.
