Appearance:

Brownish solid yellow flakes. The Sodium Hydrosulphide will decomposed and release hydrogen disulfide at its melting point. It's dissolvable in water and ethanol, presenting strong alkaline when dissolved in water and generating hydrogen disulfide when reacting with acids.

 

Applications:

Thousands of tons of NaHS are produced annually. Its main uses are in cloth and paper manufacture as a makeup chemical for sulfur used in the kraft process, as a flotation agent in copper mining where it is used to activate oxide mineral species, and in the leather industry for the removal of hair from hides and tanning. Otherwise, it could also be used in wastewater treatment, paper pulping, chemical fertilizer industry, staining for sulfite in man-made fibers industry and so on.
