Sodium sulfide 1313-82-2 Sigma-Aldrich

General description Cubic crystals of sodium sulfide (Na 2 S) are extremely hygroscopic in nature and discolor on exposure to air. Na 2 S is soluble in water, slightly soluble in alcohol and insoluble in ether. Aqueous solutions of Na 2 S are strongly alkaline.. Application Na 2 S is used for H 2 S therapy, to study its effect on the prevention of diabetes in animals.
