About sodium hydrosulfide

Sodium hydrosulfide is an inorganic substance with the chemical formula of NaHS, colorless needle like crystal. It is easy to deliquescence and decomposes at the melting point to release hydrogen sulfide. It is easily soluble in water and alcohol, and the aqueous solution is strongly alkaline. React with acid to produce hydrogen sulfide. It tastes bitter. The dye industry is used for the synthesis of organic intermediates and auxiliaries for the preparation of sulfide dyes, the leather industry is used for the depilation and tanning of raw hides, the chemical fertilizer industry is used for the removal of monomer sulfur from activated carbon desulfurizer, the mining industry is widely used in copper ore dressing, sulfite dyeing in man-made fiber production, etc. it is the raw material for the manufacture of ammonium sulfide and pesticide ethanethiol semi-finished products, as well as wastewater treatment. It is obtained by absorbing hydrogen sulfide gas from alkali sulfide or caustic soda solution.
