Sodium Sulfide, also known as disodium sulfide and sodium sulfuret, is a white solid and soluble in water. Its chemical formula is Na₂S and This compound is capable of producing alkaline solutions. When this material and its hydrates are exposed to air, they may release hydrogen sulfide gas (H₂S), which has a very strong odor resembling that of rotten eggs. Industrial sodium sulfide, due to the presence of polysulfides, is often seen in yellow and reddish brick colors.

This substance, known for its density of 1.85 gr/cm³, is used as a mineral salt in various applications. In the industry, this chemical compound finds application in different fields. For instance, in the paper and leather industry, it is used to convert rawhide into tanned leather and to purify the chemicals used in paper production.

Additionally, in mining, it is utilized for extracting metals such as copper and zinc from ores. Other uses of sodium sulfide include its application in water treatment and the removal of organic pollutants and heavy metals, its use as an auxiliary agent in chemical reactions, and its application in the pesticide industry.

However, caution must be exercised when using this material, as it may irritate the skin and eyes, and contact with large amounts of it can be hazardous, leading to adverse health effects.
