barium sulfide
Very LowTechnical/Scientific
Definition
Meaning
A chemical compound with the formula BaS, consisting of barium and sulfur.
An inorganic salt used primarily in the production of other barium compounds, as a depilatory agent in leather processing, and historically in luminous paints.
Linguistics
Semantic Notes
This is a specific chemical term. It is not used metaphorically. The spelling 'sulfide' is standard in American English, while 'sulphide' is a common British variant.
Dialectal Variation
British vs American Usage
Differences
Spelling: 'barium sulfide' (US) vs. 'barium sulphide' (UK). Pronunciation of the second element may also vary slightly.
Connotations
None beyond the technical/scientific context.
Frequency
Equally rare in both dialects, confined to chemistry, materials science, and industrial contexts.

Learning
Memory Aids
Mnemonic
Think: 'Ba' from the periodic table for Barium + 'S' for Sulfur = BaS. A 'bar' of sulfur (though it's a powder).
Conceptual Metaphor
N/A (Highly technical term with no common metaphorical mapping).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'barium sulfate' (BaSO₄, бария сульфат), a different, more common compound used in medicine and radiography.
- Ensure correct translation of 'sulfide/sulphide' as 'сульфид'.
Common Mistakes
- Misspelling as 'barium sulfate'.
- Incorrect pronunciation stressing the first syllable of 'sulfide' (e.g., /ˈsʊlfaɪd/).
- Using it in non-technical contexts where it would be incomprehensible.

FAQ
Frequently Asked Questions
Yes, it is toxic if ingested or inhaled and can react with acids to release toxic hydrogen sulfide gas.
Barium sulfide (BaS) contains sulfur in a -2 oxidation state and is reactive. Barium sulfate (BaSO₄) contains sulfur in a +6 oxidation state, is highly insoluble, and is used as a radiocontrast agent.
It is extremely rare in nature. The mineral 'barium sulfide' is essentially non-existent; it is primarily a synthetic industrial chemical.
It follows the general spelling convention for sulfur compounds: 'sulfur' and 'sulfide' in American English, 'sulphur' and 'sulphide' in British English, though the 'f' spelling is increasingly common in the UK, especially in scientific contexts.
