What is a Sodium hydrosulfide (NaHS)?

Sodium hydrosulfide (NaHS) is an inorganic compound composed of sodium ions (Na⁺) and hydrosulfide ions (HS⁻). It typically exists as a white crystalline or powdery substance and is highly soluble in water. This compound plays an important role in chemical industries and water treatment processes. Sodium hydrosulfide is used in metal refining, dyeing, leather processing, and other industrial applications. It also acts as a reducing agent in chemical reactions, promoting oxidation-reduction reactions. Additionally, it is employed in the pulp-making process in the paper industry. Sodium hydrosulfide has a strong odor, often releasing hydrogen sulfide gas (H₂S), and requires careful handling and appropriate safety measures due to its hazardous nature.
