This a soft colorless solid was known to the [[alchemy|alchemists]] as '''butter of antimony'''. It has a pungent odor, and on contact with water, it undergoes hydrolysis, forming [[antimony oxychloride]] and releasing [[hydrogen chloride]]. Thus, samples of SbCl<sub>3</sub> must be protected from moisture. :SbCl<sub>3</sub> + H<sub>2</sub>O → SbOCl + 2HCl Further indicating its [[Lewis acid]]ity, SbCl<sub>3</sub> forms [[adduct]]s with [[chloride]], e.g. [SbCl<sub>5</sub>]<sup>2−</sup>.<ref>Zarychta, B.; Zaleski, J. "Phase transitions mechanism and distortion of SbCl<sub>6</sub><sup>3−</sup> octahedra in bis(''n''-butylammonium) pentachloroantimonate(III) (C<sub>4</sub>H<sub>9</sub>NH<sub>3</sub>)<sub>2</sub>[SbCl<sub>5</sub>]". ''Z. Naturforsch. B'' '''2006''', ''61'', 1101–1109. [http://www.znaturforsch.com/ab/v61b/61b1101.pdf Abstract (PDF)]</ref> SbCl<sub>3</sub> is a [[reagent]] for detecting [[vitamin A]] and related [[carotenoid]]s in the [[Carr-Price test]]. The antimony trichloride reacts with the carotenoid to form a blue [[complex (chemistry)|complex]] that can be measured by [[colorimetry]]. Antimony trichloride has also been used to enhance the ''louche'' effect in [[absinthe]]. It has been used in the past to dissolve and remove horn stubs from calves without having to cut them off. ==References== <references/> [[Category:Chlorides]] [[Category:Antimony compounds]] [[Category:Inorganic compound stubs]] [[Category:Alchemical substances]] {{inorganic-compound-stub}} [[ar:كلوريد أنتيموان ثلاثي]] [[de:Antimon(III)-chlorid]] [[it:Cloruro di antimonio]] [[ja:塩化アンチモン]] [[pl:Chlorek antymonu(III)]] [[zh:三氯化銻]]
