High quality Sodium Pyrosulfite,Sodium metabisulphite

Description

Sodium pyrosulfite is a white or yellow crystalline powder or small crystal with strong SO2 odor and specific gravity of 1.4. It is soluble in water and acidic in aqueous solution. When exposed to strong acid, it emits SO2 to form corresponding salts. When exposed to air for a long time, it oxidizes to Na 2S 2O 6, so the product can not last long. Over 150 degrees Celsius, SO 2 is decomposed.
