| Chemical Properties |
yellow to orange powder |
| Uses |
manufacture of glass, particularly infrared-transmitting glass; manufacture of oil cloth, linoleum; in electrical semiconductors, photoconductors; as pigment; for depilating hides; in pyrotechnics. |
| General Description |
A yellow or red crystalline solid or powder. Combustible. Insoluble in water. Toxic by inhalation (dust) and ingestion. |
| Air & Water Reactions |
Insoluble in water. |
| Reactivity Profile |
ARSENIC (III) SULFIDE is dissolved by alkalis and by hydrochloric acid (slowly). Decomposed by nitric acid. May react with oxidizing agents to generate heat and products that may be flammable, combustible, or otherwise reactive. The reactions may be violent. ARSENIC (III) SULFIDE reacts with concentrated solutions of chloric acid with incandescence [Mellor Supp. II Part I:584 1956]. Generates toxic gaseous hydrogen sulfide on contact with acids. |
| Health Hazard |
(Acute and sub-acute poisoning are not common.) Repeated inhalation causes irritation of nose, laryngitis, mild bronchitis. Ingestion causes weakness, loss of appetite, gastrointestinal disturbances, peripheral neuritis, occasional hepatitis. Contact with eyes causes irritation. Irritates skin, especially where moist; if not treated, may cause ulceration. |
| Fire Hazard |
Combustible material: may burn but does not ignite readily. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form. |
