Sodium Bisulphide, chemically known as Sodium Hydrogen Sulfide (NaHS), is a yellowish liquid or crystalline solid with a strong odor of hydrogen sulfide. It is a water-soluble, alkaline compound widely used in various industrial applications for its effective reducing and sulfonation properties.
Produced typically by absorbing hydrogen sulfide gas in a sodium hydroxide solution, Sodium Bisulphide is highly reactive and should be handled with care. It plays a key role in mining, leather processing, textiles, and water treatment.
Applications
