Sodium Sulphide in Pakistan

Chemical and physical properties

• Chemical Formula:Na2Scap N a sub 2 cap S𝑁𝑎2𝑆
• Appearance: Colorless solid, but technical grades are often yellow to red due to impurities
• Odor: Rotten egg odor from the release of hydrogen sulfide (H2Scap H sub 2 cap S𝐻2𝑆) in moist air
• Melting Point:1,176∘C1 comma 176 space raised to the composed with power cap C1,176∘𝐶
• Solubility: Water-soluble 

Industrial applications

• Pulp and paper processing: Used in the Kraft process. 
• Water treatment: Functions as a wastewater treatment agent. 
• Textile industry: Used in dyeing and processing. 
• Leather processing: Used for dehairing hides. 
• Chemical manufacturing: A source of sulfide ions for synthesizing other chemicals, including rubber chemicals and sulfur dyes. 
• Metal extraction: Used in some metal extraction processes. 
• Other uses: Used in the production of heavy water for nuclear reactors and as a medication for animals. 

Safety considerations

• Sodium sulfide is corrosive and can damage skin and eyes. 
• It is harmful to aquatic life. 
• When it comes into contact with moist air, it releases toxic hydrogen sulfide gas, which should not be inhaled. 
• Proper personal protective equipment, such as gloves and safety glasses, should be worn when handling it.
