What are some uses for Sulfur?
What other elements does it react to?
Reaction of sulfur with air
Sulphur burns in air to form the gaseous dioxide sulphur(IV) oxide, SO2.
S8(s) + 8O2(g) → 8SO2(g)
Reaction of sulfur with water
Sulphur does not react with water under normal conditions.
Reaction of sulfur with the halogens
Sulphur racts with all the halogens upon heating.
Sulphur reacts with fluorine, F2, and burns to form the hexafluoride sulphur(VI) fluoride.
S8(s) + 24F2(g) → 8SF6(l) [orange]
Molten sulphur reacts with molten sulphur to form disulphur dichloride, S2Cl2. This apparently smells dreadfully. With excess chlorine and in the presence of a catalyst, such as FeCl3, Snl4, etc., it is possible to make a mixture containing an equilibrium mixture of red sulphur(II) chloride, SCl2, and disulphur dichloride, S2Cl2
S8 + 4Cl2 → 4S2Cl2(l) [orange]
S2Cl2(l) + Cl2 ⇌ 2SCl2(l) [dark red]
Reaction of sulfur with acids
Sulphur does not react with dilute non-oxidizing acids.
Reaction of sulfur with bases
Sulphur reacts with hot aqueous potassium hydroxide, KOH, to form sulphide and thiosulphate species.
S8(s) + 6KOH(aq) → 2K2S3 + K2S2O3 + 3H2O(l)
