The chemical compound with the formula Na2S is sodium sulphide, and its structure is antfluorite. These water-soluble salts have a yellow colour and produce highly alkaline solutions. The procedure yields a 10-12% sodium sulphide solution, which may be purchased in tanker loads at various percentages. The purest form of solution is obtained by the soda ash manufacturing process, which concentrates the solution to 50% or 60%. Following that, it will be fed into a flaker drum to create flakes, and it will then be packed into 25 kilogramme and 50 kg HDPE bags. Sulphur dyes, rubber chemicals, and other chemical compounds are made with it. Other uses for it include oil recovery, dye production, mineral flotation.

Used as Depilatory reagent and in pharmaceutical Industries.

Used in obtaining the sulphur Black Dyes.

Used in Ore Floatation.

Used in Engraving and also used as analytical reagent.

Used for removing sulphur in viscous Rayon Industry.

Used in Industries to remove heavy metals from waste water.
