Sodium Metabisulfite

$90
MOQ: 28  Metric Tonnes
Sample Available
 
Sodium metabisulfite is white or yellow crystalline powder or small crystal, with a strong SO2 odor, soluble in water, the aqueous solution is acidic, when contacted with strong acid, SO2 is released to form corresponding salts, and it is oxidized to Na2S2O6 when placed in the air for a long time. Therefore, the product cannot be stored for a long time. Above 150 degrees Celsius, SO2 is decomposed.
