Product Introduction:
Sodium sulfide has the chemical formula Na2S, also known as alkali sulfide, also known as smelly soda, smelly alkali. It is a colorless or slightly purple prismatic crystal. It has an eggy smell. The specific gravity of the hydrate is 2.427. The melting point is 52°C and it decomposes at 920°C. It reacts strongly alkaline when dissolved in water. It is used as the main agent in the photo brown toning method, because sodium sulfide can react with silver salt bleached by potassium ferrocyanide to produce brown silver sulfide. In addition, it can be used in the blackening liquid thickened by copper bromide-silver nitrate or red blood salt-lead nitrate in wet plate photography in the printing industry.
Sodium sulfide usually exists in the form of nonahydrate Na2S·9H2O. Both the anhydrous and nonahydrate are colorless and soluble solids, and hydrolysis in aqueous solution is strongly alkaline. When exposed to air, sodium sulfide will release toxic hydrogen sulfide gas with the smell of rotten eggs. The formula weight of sodium sulfide nonahydrate is 240.18. Colorless crystals, easy to deliquesce, soluble in water and ethanol. The solution after hydrolysis is alkaline and corrosive. When it comes into contact with skin or keratin, it can soften and dissolve it and cause hair to fall off.
Soluble in crystal water at 50°C. Turns yellow when exposed to light and can be oxidized to sodium thiosulfate in the air. Sodium polysulfide (Na2Sx, x=2, 3, 4 or 5) is generated after adding sulfur to the aqueous solution. It is used to prepare sulfur dyes, leather depilatories, and as a reducing agent in the organic chemical industry. Sodium sulfate can be reduced to sodium sulfide by mixing sodium sulfate with carbon and calcining. It should be stored in a ventilated, dry place, away from light, and the container should be sealed to prevent moisture and deterioration. Keep away from heat sources and living areas, and isolate from explosives, oxidants, etc. Wear protective equipment and rubber gloves when loading and unloading. Firefighting can use water or sand.
