Sodium Hydrosulfide is an economical form of reactive sulfur that is typically a light-yellow colored solution with the accompanying odor of rotten eggs. Hydrogen Sulfide (H₂S), a toxic gas, is evolved upon contact of Sodium Hydrosulfide with acids.

Content : 29-31 wt%
Density, : 20°C 1.185-1.205 kg/l
Na₂CO₃ : ≤ 0.5 wt%
Na₂S ≤ : 0.3 wt%
Sodium hydrosulfide is used as a reactive form of sulfur and acts as an intermediate in the production of other chemicals, including thio-chemicals used in textile processing, in the production of flame retardant resins, and in vulcanization accelerators. Sodium hydrosulfide is also used as a processing aid in the production of a variety of industrial products. It is a de-hairing agent in the production of fine leathers. In mining, it is a flotation agent, helpful in the precipitation of metals from ore slurries. Sodium hydrosulfide is also valuable as a raw material in the production of heat-resistant plastics for the auto and electronic industries. In paper making, Sodium hydrosulfide is used to add sulfidity to cooking liquor in kraft pulp mills.
Mining: NaHS acts as a flotation reagent, particularly in copper mining, where it helps to activate oxide mineral species.
