Sodium metabisulfite is white or yellow crystalline powder or small crystals, with a strong SO2 odor, specific gravity 1.4, soluble in water, the aqueous solution is acidic, and when it comes in contact with strong acid, it will release SO2 and generate corresponding salts. It will oxidize if left in the air for a long time. It becomes Na2S2O6, so the product cannot be stored for a long time. Above 150 degrees Celsius, SO2 is decomposed.
