Sodium sulfide is the chemical compound with the formula Na₂S, or more commonly its hydrate Na₂S·9H₂O. Both are colorless water-soluble salts that give strongly alkaline solutions. When exposed to moist air, Na₂S and its hydrates emit hydrogen sulfide, which smells like rotten eg...
It has been now developed of the method for making sulfuric acid, sulfur, soda ash, ammonium sulfate and other products with sodium sulfate. However, due to the high cost of these methods, it has not yet been widely applied. It has been commonly used by laboratory system for using sodium...

The meaning of SODIUM SULFIDE is a sulfide of sodium; especially : a crystalline compound Na2S usually obtained by heating sodium sulfate with coal or hydrogen and used in dehairing hides, in the manufacture of sulfur dyes, as a solvent for these dyes, a
SODIUM SULFATE, with the chemical formula Na2SO4 and CAS registry number 15124-09-1, is a compound widely used in various industries. This inorganic salt, also known as Glauber's salt, is characterized by its sodium and sulfate ions. It is commonly used as a filler in detergents, as a...
(I) chloride, silicon tetrachloride, silver fluoride, tin(IV) chloride, tin(IV) iodide (with sulfur), tin(II) chloride, sulfur dibromide, sulfur dichloride, thallium(I) bromide, vanadium pentachloride, phosphorus pentachloride, phosphorus tribromide, and zinc bromide [Mellor 2 Supp. 2:497 1961]...
Sodium sulfide, thiophosphate or Cys can function as sulfur donors in vitro, and sodium sulfide provides the highest activity [54,69]. However, the catalytic efficiency (kcat/Km) of SepCysS with sulfide is about 500-fold lower than that of SepRS for phosphoserylation of tRNACys; therefore,...
At present, the Hargreaves–Robinson process to produce hydrogen chloride provides a significant proportion of the by-product sodium sulfate in Europe, and at least one plant in the U.S.A. still uses this process. Air, steam, and sulfur dioxide are passed over a heated bed of porous salt ...
What will be the formula of a compound formed by aluminum and sulfur? What is the chemical element symbol of sodium? What is the lead II oxide formula? What is the common name for oxygen oxide? What is the name for the compound with the formula As2O5? What is the chemic...
The crystal sodium sulfide segment dominated the market in 2023. Sodium sulfide, a colorless solid crystal with yellow to brick red technical grades due to polysulfides, is utilized in rubber chemicals, oil recovery, ore flotation, dye manufacture, sulfur dyes, and detergent ...
