Oct 24, 2023 · Sodium sulfide. [Na+]. [Na+]. [S-2] Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Sodium sulfide is the chemical compound with the chemical formula Na2S, or more commonly its nonahydrate form Na2S·9H2O .
General Description. Sodium sulfide, anhydrous is a yellow to brick red crystalline mass or fused solid with an odor of rotten eggs. If exposed to moist air it is liable to spontaneous heating and may cause ignition of nearby combustible material. It absorbs moisture from the air.
Sodium sulfide is a chemical compound with the formula Na2S, or more commonly its hydrate Na2S·9H2O. Both the anhydrous and the hydrated salts in pure crystalline form are colorless solids, although technical grades of sodium sulfide are generally yellow to brick red owing to the presence of polysulfides and commonly supplied as a crystalline ...
Sodium sulfide is a chemical compound which has a strong alkaline solution. It is exposed in the moisture air that means it emits the strong rotten eggs smell. By the carthothermic reaction the coal is used to produce the sodium sulfide. They are colourless in the both forms such as anhydrous and hydrated salts.
Sodium sulfide. Molecular Formula Na 2 S; Average mass 78.045 Da; Monoisotopic mass 77.951607 Da; ChemSpider ID 14120
Though the chemistry seems simple, there are four principal steps involved in practical processes to obtain the good quality products: (1) preparation of sodium sulfide from aqueous sodium hydrosulfide and caustic in a polar solvent; (2) dehydration of sodium sulfide stream; (3) production of PPS from dichlorobenzene and sodium sulfide; and (4 ...
