Molten sulfur reacts with hydrogen to form hydrogen sulfide. Hydrogen sulfide is a gas with a characteristic rotten egg smell. Toxic.
S + H2 = H2S
Hydrogen sulfide in a sufficient amount of oxygen completely burns out with the formation of water and sulfur dioxide.
2 H2S + 3 O2 = 2 H2O + 2 SO2
Sulfur dioxide, when passed through a sodium hydroxide solution, forms a salt of weak sulfurous acid – sodium sulfite.
2 NaOH + SO2 = Na2SO3 + H2O
Also, sodium sulfite can be obtained by passing sulfur dioxide through sodium carbonate.
Na2CO3 + SO2 = Na2SO3 + CO2
