Product Description Product Name: Sodium SulfideOther Names:Sodium monosulfide; Sodium sulfide (Na2S); sodium sulfuret; Sodium Sulphide; Disodium monosulfide; Disodium sulfide; disodiummonosulfide; disodiumsulfide; Hesthsulphid; Na2-S; disodium sulfanide; sodium sulfidosodiumMolecular Formula: Na2SUN No.: 1849HS No.:2830101000CAS No.: 1313-82-2EINECS No.: 215-211-5Hazard Class: 8Purity: 60%Appearance: Yellow and Red FlakesGrade Standard: Industrial GradePhysical and Chemical PropertiesSodium sulfide is the chemical compound with the formula Na2S, or more commonly its hydrate Na2S·9H2O. Both the anhydrous and the hydrated salts are colorless solids, They are water-soluble, giving strongly alkaline solutions. When exposed to moist air, Na2S and its hydrates emit hydrogen sulfide, which smells like rotten eggs. Some commercial samples are specified as Na2S·xH2O, where a weight percentage of Na2S is specified. Commonly available grades have around 60% Na2S by weight, which means that x is around 3. Such technical grades of sodium sulfide have a yellow appearance owing to the presence of polysulfides. These grades of sodium sulfide are marketed as 'sodium sulfide flakes'.Grade Standard: Industrial GradeITEMSTANDARDSTANDARDSTANDARD IISTANDARD IIISTANDARDSTANDARDFe10ppm max20ppm max30ppm max80ppm max150ppm max1500ppm maxNa2S60%min60%min.60%min.60%min.60%min.60%min.Water insolubles0.03%max0.10%max.0.18%max.0.20%max.0.30%max.0.40%max.Na2CO31.80%max1.80%max.1.80%max.2.00%max.3.00%max.5.00%max.Na2SO31.00%max1.80%max.1.80%max.2.00%max.2.00%max.2.00%max.Na2S2O32.00%max2.00%max.2.00%max.2.00%max.2.00%max.2.00%max.Colour YellowREDNote: The above specification meets requirement of GB/T 10500-2009,and also accords with European and American Standards.

Keep container closed when not in use. Store in a tightly closed container. Keep from contact with oxidizing materials. Keep away from strong acids. Store protected from moisture.Like sodium hydroxide, sodium sulfide is strongly alkaline and can cause skin burns. Acids react with it to rapidly produce hydrogen sulfide, which is highly toxic.
