Sodium Sulfide CAS#1313-82-2Product Description:  Sodium sulfide is the chemical compound with the system Na₂S, or greater many times its hydrate Na₂S·9H₂O. Both are colorless water-soluble salts that supply strongly alkaline solutions. When uncovered to moist air, Na₂S and its hydrates emit hydrogen sulfide, which smells like rotten eggs. Sodium sulfide, anhydrous is a yellow to brick pink crystalline mass or fused solid. If uncovered to moist air, it absorbs moisture from the air, and it is in charge to spontaneous heating and might also motive ignition of close by flamable material.

Products Description of Sodium sulfate CAS#7757-82-6Sodium sulfate is an important chemical raw material and the main raw material for producing chemical products such as sodium sulfide and sodium silicate. Sodium sulfate is also called glauber's salt, anhydrous sodium sulfate, and anhydrous sodium sulfate. White monoclinic crystals are fine crystals or powders. Relative density is 2.68, melting point is 884℃. Soluble in water, and the aqueous solution is neutral. Soluble in glycerol, insoluble in ethanol, exposed to air, it easily absorbs water to become hydrated sodium sulfate.
