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
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...
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...

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,...
Sodium hydrosulfite is manufactured in the US by several process routes: the reaction of sodium formate (HCOONa) with caustic soda and sulfur dioxide, in an aqueous methanol solution; by reducing sodium bisulfite (NaHSO3) with electrolytically produced sodium amalgam (NaxHgx); or by reacting sulf...
(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]...
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 ...
Sodium Metabisulfite (sodium bisulfite anhydrous, sodium pyrosulfate, SMBS, MBS) is a white inorganic crystalline compound with the chemical formula Na2S2O5. Sodium metabisulfite is an inorganic compound used as an antioxidant, a preservative in food, or for dichlorination in a broad range of ...
