Formation of Hydrogen Sulfide

H2 + S → H2S

Ikhtisar

Hydrogen gas reacts with sulfur to form hydrogen sulfide, the gas responsible for the characteristic smell of rotten eggs. This mildly exothermic reaction occurs at elevated temperatures. Hydrogen sulfide is highly toxic even at low concentrations.
