Phosphorus pentasulfide is the inorganic compound with the formula P 2 S 5 or P 4 S 10 . This yellow solid is the one of two phosphorus sulfides of commercial value. Samples often appear greenish-gray due to impurities. It is soluble in carbon disulfide but reacts with many other solvents such as alcohols, DMSO, and DMF. [3]
Phosphorus sulfides comprise a family of inorganic compounds containing only phosphorus and sulfur.These compounds have the formula P 4 S n with n ≤ 10. Two are of commercial significance, phosphorus pentasulfide (P 4 S 10), which is made on a kiloton scale for the production of other organosulfur compounds, and phosphorus sesquisulfide (P 4 S 3), used in the production of "strike anywhere ...
Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of 2.05. In accordance with periodic trends, it is more electronegative than tin or bismuth, and less electronegative than tellurium or arsenic.
Antimony pentasulfide is an inorganic compound of antimony and sulfur, also known as antimony red. It is a nonstoichiometric compound with a variable composition. Its structure is unknown. [2] Commercial samples are contaminated with sulfur, which may be removed by washing with carbon disulfide in a Soxhlet extractor.
Potassium pentasulfide is the inorganic compound with the formula K 2 S 5. It is a red-orange solid that dissolves in water. It is a red-orange solid that dissolves in water. The salt decomposes rapidly in air.

Arsenic pentasulfide is prepared by precipitation from an acidic solution of soluble As(V) salts by treatment with hydrogen sulfide. [3] It may be also prepared by heating a mixture of arsenic and sulfur, extracting the fused mass with an ammonia solution and reprecipitating arsenic pentasulfide at low temperature by addition of hydrochloric acid.
