What are the effects of sodium sulfide hydrolysis?
Sulfides in water are prone to hydrolysis, releasing H₂S into the air. Inhaling large amounts of H₂S can immediately cause nausea, vomiting, difficulty breathing, suffocation, and severe toxic effects. Exposure to air concentrations of 15–30 mg/m³ may lead to conjunctivitis and damage to the opti...Read more -
What are the elements of sodium sulfide in water?
Sodium sulfide in water include dissolved H₂S, HS⁻, S²⁻, as well as acid-soluble metal sulfides present in suspended solids, and undissociated inorganic and organic sulfides. Water containing sulfides often appears black and has a pungent odor, primarily due to the continuous release of H₂S gas. ...Read more -
How does sodium sulfide affect the environment?
Sodium Sulfide Impact on the Environment: I. Health Hazards Routes of Exposure: Inhalation, ingestion. Health Effects: This substance can decompose in the gastrointestinal tract, releasing hydrogen sulfide (H₂S). Ingestion may lead to hydrogen sulfide poisoning. It is corrosive to the skin and ey...Read more -
What is the role of sodium sulfide in the paper industry?
Sodium sulfide is highly effective in deinking within the paper industry; used for debairing and tanning in leather processing; and employed in wastewater treatment to rapidly precipitate harmful substances, ensuring effluent meets discharge standards. Sodium sulfide is also indispensable in chem...Read more -
What is the production method of sodium sulfide?

Which elements are found in sodium sulfide?
Sodium sulfide, an inorganic compound also also known as odorous alkali, odorous soda, yellow alkali, or sulfide alkali, is a colorless crystalline powder in its pure form. It is highly hygroscopic and readily soluble in water, yielding an aqueous solution that exhibits strongly alkaline properti...Read more -
Is sodium sulfide soluble in water?
Sodium sulfide is a variable-color crystal with a repulsive odor. It reacts with acids to produce hydrogen sulfide. Its aqueous solution is strongly alkaline, hence it is also known as sulfurated alkali. It dissolves sulfur to form sodium polysulfide. Industrial products often appear as pink, red...Read more -
