Sodium sulfide is also called stinky alkali, stinky soda, yellow alkali, and alkali sulfide. Sodium sulfide is an inorganic compound, and pure sodium sulfide is a colorless crystalline powder. It has strong moisture absorption and is easily soluble in water. The aqueous solution is strongly alkaline. It can cause burns when touching the skin and hair. So sodium sulfide is commonly called alkali sulfide.
Sodium sulfide deliquescence in the air, and carbonation and deterioration, continuously releasing hydrogen sulfide gas. Industrial sodium sulfide is pink, brown-red, and ocher due to impurities. The specific gravity, melting point, and boiling point also vary due to the influence of impurities.

Sodium sulfide is primarily used in the kraft process in the pulp and paper industry.
It is used in water treatment as an oxygen scavenger agent and also as a metals precipitant; in chemical photography for toning black and white photographs; in the textile industry as a bleaching agent, for desulfurising and as a dechlorinating agent; and in the leather trade for the sulfitisation of tanning extracts. It is used in chemical manufacturing as a sulfonation and sulfomethylation agent. It is used in the production of rubber chemicals, sulfur dyes and other chemical compounds. It is used in other applications including ore flotation, oil recovery, making dyes, and detergent. It is also used during leather processing, as an unhairing agent in the liming operation.
Application
1. Used in the production of sulfur dyes in the dye industry. In printing and dyeing industry, it is used as a dyeing aid for dissolving sulfur dyes.
2. It can be used to remove alkali-soluble heavy metal impurities such as zinc in alkaline etching solution.
3. Sodium sulfide can also be used for the treatment of conductive layer in direct electroplating.
4. Used as a corrosion inhibitor.
5. Used in the manufacture of sulfur dyes, leather depilatory, metal smelting, photography, rayon denitration, etc.
1, in the dye industry for the production of vulcanized dyes, vulcanized blue and vulcanized blue raw materials. The printing and dyeing industry is used as a dye aid for dissolving vulcanized dyes. In the leather industry, it is used for hydrolyzing to depilate raw skin. It is also used for preparing sodium polysulfide to accelerate the water soaking of dry skin and help it to be soft. The paper industry uses it as a cooking agent for paper. The textile industry is used for the reduction of denitrification and nitrification of man - made fibres and as mordants for dyeing cotton fabrics. The pharmaceutical industry is used for the production antipyretics. In addition, it is also used to produce sodium thiosulfate, sodium thiohydride, sodium polysulfide and so on.
2. Adding an appropriate amount of sodium sulfide to the alkaline etching solution of aluminum and alloy can obviously improve the etching surface quality, and it can also be used for the removal of alkaline soluble heavy metal impurities such as zinc in the 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 to achieve the purpose of forming a good conductive layer on the non-metallic surface.
4. Used as an inhibitor. It is also the raw material of sodium thiosulfate, sodium polysulfide, sulfide dyes and so on.
5. Used for manufacturing vulcanized dyes, leather dehairing agents, metal smelting, photography, rayon denitration, etc
