Sodium metabisulfite is a white or yellow crystalline powder or a small crystal with a strong SO2 odor. The specific gravity is 1.4. It dissolves in water and the aqueous solution is acidic. When it comes into contact with strong acid, SO2 is released and the corresponding salt is generated. If it is left in the air for a long time, it is oxidized. As Na2S2O6, so the product can not exist for a long time. Above 150 degrees Celsius, SO2 is decomposed.
