Product Name:Hydrogen sulfide
English Name:Hydrogen sulfide
CAS No.:7783-06-4
Aliases:Hydrosulfuric acid, Sulfuretted hydrogen
Molecular Formula:H2S
Physical Properties:Colorless flammable acidic gas with a characteristic rotten-egg odor. Melting point: -85.5°C; boiling point: -60.3°C. Gas density: approximately 1.52 g/L (at standard conditions); relative density (air = 1): approximately 1.19. Soluble in water, forming a weakly acidic solution.
Uses:Used industrially for the production of high-purity sulfur via reaction with sulfur dioxide. In chemical analysis, it is employed for the identification of metal ions; for instance, it reacts with silver to form black-brown silver sulfide, allowing the detection of silver. It is also used as a raw material for preparing various metal sulfides and other chemical products.
