Appearance:Hydrogen sulfide appears as a colorless gas having a strong odor of rotten eggs. Boiling point -60.2°C. Shipped as a liquid confined under its own vapor pressure. Density (liquid) 8.3 lb / gal. Contact with the unconfined liquid can cause frostbite by evaporative cooling. Gas is very toxic by inhalation. Fatigues the sense of smell which cannot be counted on to warn of the continued presence of the gas. Prolonged exposure of closed containers to heat may result in their violent rupturing and rocketing. Rate of onset: Immediate & Delayed Persistence: Minutes to hours Odor threshold: 0.1 ppm Source/use/other hazard: Disinfectant lubricant/oils; interm for HC manufacture; deadens sense of smell.
Density:0.9539 g/cm3
Melting Point:-85.49 °C
Boiling Point:-60.33 °C
Flash Point:-17℃
Water Solubility:1g dissolves in H2O: 187mL (10°C), 242mL (20°C), 314 (30°C) [MER06]
Storage Conditions:2-8°C
Vapor Pressure:252 psi ( 21 °C)
Vapor Density:1.19 (15 °C, vs air)
Toxicity:Inhalation-rat LC50: 666 mg/m3; inhalation-mouse LC50: 951 mg/m3/1 hour
Flammability characteristics:Flammable; burning produces toxic nitrogen oxide fumes
Explosive limit:6%
Odor:Strong odor of rotten eggs [Note: Sense of smell becomes rapidly fatigued & can NOT be relied upon to warn of the continuous presense of hydrogen sulfide].
Taste:Sweetish taste
PH:pH freshly prepared water soln: 4.5
