Hydrogen sulfide is an inorganic compound with the chemical formula H₂S. Under normal circumstances, it is a colorless, flammable acidic gas with a foul odor at low concentrations, resembling a rotten egg; When the concentration is high, there is no odor (because high concentrations of hydrogen sulfide can paralyze the olfactory nerve). It can dissolve in water, and at 0 ° C, 1 mole of water can dissolve about 2.6 moles of hydrogen sulfide. The aqueous solution of hydrogen sulfide is called hydrogen sulfate, which is a weak acid. When it is heated, hydrogen sulfide escapes from the water. Hydrogen sulfide is an acute and highly toxic substance, and inhaling a small amount of high concentration hydrogen sulfide can be fatal in a short period of time. Low concentrations of hydrogen sulfide have effects on the eyes, respiratory system, and central nervous system.
