Common Mistakes When Using “arsenic disulfide”
- Misspelling as 'arsenic disulphide' (UK variant is acceptable but 'disulfide' is standard IUPAC).
- Pronouncing 'disulfide' with the stress on the first syllable (/ˈdaɪ.sʌl.faɪd/, not /daɪ.ˈsʌl.faɪd/).
- Confusing it with arsenic trioxide (a white powder), which is far more commonly referenced as 'arsenic' poison.
FAQ
Frequently Asked Questions
No. 'Arsenic' commonly refers to the element (As) or its oxide (As₂O₃). Arsenic disulfide (As₂S₂) is a specific, less common compound, a red mineral known as realgar.
You might encounter it in advanced chemistry or geology studies, in art history texts discussing historical pigments, or in material safety documentation for mineral collections.
It is toxic, as it contains arsenic. It poses health risks through inhalation of dust or ingestion. It should only be handled by trained professionals with appropriate safety equipment.
Both are arsenic sulfides. Realgar is arsenic disulfide (As₂S₂), orange-red. Orpiment is arsenic trisulfide (As₂S₃), yellow. They are different minerals.
