Physical
and chemical
properties: pure sulfide anhydrous is white cubic crystals
or granules. Highlyhygroscopic, easy to
change, the air is unstable. The relative
density of 1.856 (14 ° C), melting
point of1180 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
