  Physical and chemical properties: pure sulfide anhydrous is white cubic crystals or granules. Highly hygroscopic, easy to change, the air is unstable. The relative density of 1.856 (14 ° C), melting point of 1180 degrees Celsius. Solubility for 15.4g/100ml of water dissolved in water (10 degrees Celsius and 90 degrees Celsius solubility 57.2g/100ml in water), the solution is alkaline. Slightly soluble in alcohol, insoluble in ether. Dissolved in water is strongly alkaline and can cause burns when touching the skin and hair, and it is also known as sodium sulfide. Soluble sulfur generated sodium polysulfide. Sodium sulfide is corrosive, toxic, easily oxidized in air to generate sodium thiosulfate. Sodium sulfide in the air deliquescence and carbonation deterioration continuous release of hydrogen sulfide gas. Industrial sulfide due to the presence of impurities in the color pink, brown-red, yellowish brown color blocks. Its specific gravity, melting point, boiling point, is also impurities affect different.
