Sulfur Properties of Sulfur Sulfur burns with blue flame, is insoluble in water, and forms polyatomic allotropes. Learning Objectives Describe the properties of sulfur. Key Takeaways Key Points Sulfur forms polyatomic molecules with different chemical formulas.
Its best-known allotrope is octasulfur, S 8 , which is a soft, yellow solid with faint odor. At temperatures higher than boiling point for octasulfur, depolymerization occurs. Stable allotropes are excellent electrical insulators.
Sulfur burns with a blue flame, forming sulfur dioxide with suffocating odor. It is insoluble in water but soluble in carbon disulfide.
Higher ionization states exist only with strong oxidants such as fluorine, oxygen, and chlorine. Key Terms depolymerization : The decomposition of a polymer into smaller fragments. Sulfur Compounds Sulfur forms stable compounds with most elements except the noble gases. Learning Objectives Discuss several examples of sulfur compounds. Key Takeaways Key Points Hydrogen sulfide is mildly acidic in water and is extremely toxic.
Sulfur can form chains with itself catenation. Polysulfides are formed by reduction of elemental sulfur. Polysulfanes are protonated polysulfides. Reduction of sulfur gives sulfide salts. Burning sulfur forms the principal sulfur oxides. The sulfur oxides form numerous oxyanions, which are related to numerous acids. Oleum is a solution of pyrosulfuric acid and sulfuric acid. Peroxides convert sulfur into unstable sulfoxides. Sulfur compounds with halogens include sulfur hexafluoride, sulfur dichloride, and chlorosulfuric acid.
Thionyl chloride is a common reagent in organic synthesis. Tetrasulfur tetranitride and thiocyanates are compounds of sulfur and nitrogen. The principal ores of many metals are sulfides. Tarnishing is the process of metal corrosion by sulfur. Sulfur-containing organic compounds include thiols the sulfur analogs of alcohols and thioethers the sulfur analogs of ethers. Compounds with carbon—sulfur bonds are uncommon. These metrics are regularly updated to reflect usage leading up to the last few days.

The autoignition temperature of carbon disulfide is degree F; all surfaces in the laboratory must be below this temperature. Failing to provide adequate ventilation during use of carbon disulfide can lead to inhalation, fire and explosions. Avoid skin contact with carbon disulfide, as it can cause second or third-degree burns.
Use an emergency shower if skin contact occurs, followed by soap and water washing of the affected area. Immediately remove any clothes that have come in direct contact with carbon disulfide. Cease working immediately if you experience dizziness, headache, nausea, euphoria or convulsions, as these are symptoms of acute inhalation of carbon disulfide.
Eating, drink, taking medication, or any other activity involving ingestion or the risk of ingestion should not be done near carbon disulfide to prevent poisoning. Jason Williams has been involved in journalism since as both a writer and an editor.
