XLogP3:0.38050
Appearance:Sodium hydrosulfide, solution appears as a colorless to light-yellow liquid. Corrosive to metals and tissue. It is used in paper pulping, manufacturing dyes and dehairing hides.
Density:1.79 g/cm3
Melting Point:350 °C
Boiling Point:212° F at 760 mm Hg (approx.) (USCG, 1999)
Flash Point:90ºC
Water Solubility:H2O: 620 g/L (20 ºC)
Storage Conditions:Keep containers tightly closed in a well ventilated area away from food products. Keep away from heat and water. Store at temper
Vapor Pressure:negligible
Odor:ODOR OF HYDROGEN SULFIDE
Experimental Properties:Needles of flakes, mp 55 °C. Completely and rapidly soluble in water, alcohol, ether /DIHYDRATE/.|Shiny rhombs, mp 22 °C/TRIHYDRATE/.|When exposed to air, sodium hydrosulfide undergoes autoxidation and gradually forms polysulfur, thiosulfate, and sulfate. It also absorbs carbon dioxide, forming sodium carbonate.
Air and Water Reactions:The solution continuously and slowly evolves gaseous hydrogen sulfide. Rate of evolution is increased by acids.
Reactive Group:Sulfides, Inorganic
Reactivity Alerts:Strong Reducing Agent
Reactivity Profile:A chemical base. Reacts with acids to release flammable and toxic gaseous hydrogen sulfide. As long as the solution is kept strongly alkaline, pH > 10, there is very little release of H2S. At pH = 7, the percent concentration of H2S released is close to 80%.
Corrosivity:Corrodes most metals. /Sodium Hydrosulfide Solution/
