Arsenic trisulfide is the inorganic compound with the formula As 2 S 3. It is a dark yellow solid that is insoluble in water. It is a dark yellow solid that is insoluble in water. It also occurs as the mineral orpiment (Latin: auripigmentum), which has been used as a pigment called King's yellow.
Arsenic trisulfide, As 2 S 3, the mineral orpiment; Arsenic pentasulfide, As 2 S 5, similar structure to phosphorus pentasulfide (β-P 2 S 5) Tetraarsenic tetrasulfide, As 4 S 4 (2 isomers): the mineral realgar; the mineral pararealgar; Tetraarsenic trisulfide, As 4 S 3, the mineral α- or β- dimorphite
Any arsenic present would appear as arsenic trioxide and then could be subjected to Metzger's test. The most common test (and used even today in water test kits) was discovered by Samuel Hahnemann. It would involve combining a sample fluid with hydrogen sulfide (H 2 S) in the presence of hydrochloric acid (HCl). A yellow precipitate, arsenic ...
In organic and organometallic chemistry, trisulfide is the functional group R-S-S-S-R. Examples include: Diallyl trisulfide; Dimethyl trisulfide; Trisulfane (hydrogen trisulfide) Some inorganic compounds are also named trisulfides to reflect their stoichiometry. Examples include: Antimony trisulfide; Arsenic trisulfide; Bismuth trisulfide ...
Realgar (/ r i ˈ æ l ɡ ɑːr,-ɡ ər / ree-AL-gar, -gər), also known as arsenic blende, ruby sulphur or ruby of arsenic, is an arsenic sulfide mineral with the chemical formula α-As 4 S 4. It is a soft, sectile mineral occurring in monoclinic crystals, or in granular, compact, or powdery form, often in association with the related ...
In As 4 S 10, arsenic has a formal oxidation state of +2 in As 4 S 4 which features As-As bonds so that the total covalency of As is still 3. [6] Both orpiment and realgar, as well as As 4 S 3, have selenium analogs; the analogous As 2 Te 3 is known as the mineral kalgoorlieite, [7] and the anion As 2 Te − is known as a ligand in cobalt ...
In its standard state arsine is a colorless, denser-than-air gas that is slightly soluble in water (2% at 20 °C) [1] and in many organic solvents as well. [citation needed] Arsine itself is odorless, [5] but it oxidizes in air and this creates a slight garlic or fish-like scent when the compound is present above 0.5 ppm. [6]
The group 1 alkali metals and the group 2, alkaline earth metals, form arsenides with isolated arsenic atoms. They form upon heating arsenic powder with excess sodium gives sodium arsenide (Na 3 As). The structure of Na 3 As is complex with unusually short Na–Na distances of 328–330 pm which are shorter than in sodium metal.
