Sodium sulfide, also known as smelly alkali, smelly soda, alkali sulfide, is an inorganic compound, the chemical formula is Na2S, the appearance of colorless crystalline powder, soluble in water, insoluble in ether, slightly soluble in ethanol. It burns when touched on skin and hair, so sodium sulfide is commonly known as alkali sulfide. When exposed to air, sodium sulfide emits toxic hydrogen sulfide gas that smells like rotten eggs. Industrial sodium sulfide due to impurities in its color is pink, brown red, earth yellow.

| CONCLUSION: QUALIFIED |
1, used in the dye industry for the production of sulfur dyes, is the raw material of sulfur blue and sulfur blue. Printing and dyeing industry used as an aid to dissolve sulfide dyes. Used in the tanning industry for hydrolysis to remove hair from raw hides. In addition, it is also used to produce sodium thiosulfate, sodium hydrosulfide-, sodium polysulfide and so on.
2, adding an appropriate amount of sodium sulfide in aluminum and alloy alkaline etching solution can significantly improve the quality of the etching surface, and can also be used for the removal of alkali-soluble heavy metal impurities such as zinc in alkaline etching solution.
3, sodium sulfide can also be used in direct electroplating conductive layer treatment, through the reaction of sodium sulfide and palladium to form colloidal palladium sulfide to achieve the purpose of forming a good conductive layer on the non-metallic surface.
4, used as corrosion inhibitor. It is also a raw material for sodium thiosulfate, sodium polysulfide, sulfide dyes, etc.
5, used in the manufacture of sulfur dyes, leather hair removal agents, metal smelting, photography, rayon denitrification and so on.
