MF:
Na2S Name: Sulfide sodium Molecular Weight: *8.*4 Product quality:
meet the GB*********8 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.**6 (*4 ° C), melting point of ***0 degrees Celsius.
Solubility for *5.4g/**0ml of water dissolved in water (*0 degrees
Celsius and *0 degrees Celsius solubility *7.2g/**0ml 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.
