Meaning and Definition
Any of a series of acids of the type Sx(OH)2, derived from hydrogen sulfide by replacement of hydrogen atoms with sulfur atoms, typically in inorganic chemistry contexts.
In historical chemistry, refers specifically to dithionic acid (H2S2O6) and trithionic acid (H2S3O6), but the series includes acids with more sulfur atoms. More broadly, any compound with the general formula Sx(SO3H)2.
Dialectal Variation
British vs American Usage
Differences
No major lexical or spelling differences. Usage is identical in professional scientific contexts between regions.
Connotations
Identical connotations of being a highly technical, inorganic chemistry term.
Frequency
Extremely rare in both varieties. Its use is confined to chemistry, and even there, it is a niche term from classical inorganic chemistry, encountered primarily in textbooks and historical papers.

FAQ
Frequently Asked Questions
Like many strong inorganic acids, specific thionic acids can be corrosive and hazardous. Always consult the relevant material safety data sheet (MSDS) for the specific compound.
No. Sulfuric acid (H2SO4) is a single, common acid. Thionic acid refers to a series of acids with varying numbers of sulfur atoms (e.g., H2S2O6, H2S3O6).
In a university-level advanced inorganic chemistry course, specifically in modules covering sulfur chemistry or classical inorganic synthesis.
It is a highly specialized technical term for a class of compounds that are not commonly encountered outside of specific research or educational contexts in sulfur chemistry.
Any of a series of acids of the type Sx(OH)2, derived from hydrogen sulfide by replacement of hydrogen atoms with sulfur atoms, typically in inorganic chemistry contexts.
Thionic acid is usually technical/scientific in register.
