Meaning and Definition
A highly toxic, colourless to yellow oily liquid with the chemical formula AsCl₃, formed from arsenic and chlorine.
In chemistry, it is used as an intermediate in the manufacture of other arsenic compounds, in ceramics, and historically in some military applications. It hydrolyzes in moist air to release hydrochloric acid fumes.

FAQ
Frequently Asked Questions
No. 'Arsenic' commonly refers to the element or its various compounds. Arsenic trichloride (AsCl₃) is one specific, highly toxic liquid compound of arsenic and chlorine.
You would most likely encounter it in technical settings: chemistry laboratories, industrial chemical plant documentation, advanced chemistry textbooks, or material safety data sheets (MSDS/SDS).
The prefix 'tri-' indicates three atoms of chlorine are bonded to one atom of arsenic in the molecule (AsCl₃). This follows standard chemical nomenclature.
Virtually never. It is an industrial and laboratory chemical intermediate, not a consumer product, due to its extreme toxicity and reactivity with water.
A highly toxic, colourless to yellow oily liquid with the chemical formula AsCl₃, formed from arsenic and chlorine.
Arsenic trichloride is usually technical/scientific in register.
Arsenic trichloride: in British English it is pronounced /ˌɑː.sən.ɪk traɪˈklɔː.raɪd/, and in American English it is pronounced /ˌɑːr.sən.ɪk traɪˈklɔːr.aɪd/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: 'Tri' means three, like a tricycle has three wheels. Arsenic Trichloride is one Arsenic atom bonded to three Chlorine atoms (AsCl₃).
Conceptual Metaphor
Often framed as a 'precursor' or 'intermediate' (a stepping-stone to other chemicals) and a 'hazard' (requiring containment and caution).
