【Sodium Metabisulfite details】:
【Name】： Sodium Pyrosulfite
【Molecular formula】：Na2S2O5
【Molecular weight】：190.09
【CAS No. 】：7681-57-4
【Hs Code】： 2832 1000
【Physical Character】：White or yellowish crystalline powder. Relative density is 1.4. Soluble in water (20 ℃ for 54 g / 100 ml of water, 100 ℃ for 81.7 g / 100 ml of water), acidic aqueous solution, soluble in glycerin, slightly soluble in alcohol. It is easy to decompose when affected by damp, and easy to oxidize into sodium sulfate when exposed to air. Its contact with strong acid will release sulfur dioxide and generate the corresponding salts. It will decompose when heated to 150 ℃.
