Product Description

Free Sample Industrial Grade 7681-57-4 Food Grade Sodium Metabisulfite Powder 

Sodium metabisulfite is a white or yellow crystalline powder or small crystal with a strong SO2 odor, a specific gravity of 1.4,soluble in water, and the aqueous solution is acidic. When it is in contact with a strong acid, it releases SO2 to form a
corresponding salt. When it is left in the air, it oxidizes. It is Na2S2O6, so the product cannot be stored for a long time. Above150 degrees Celsius, SO2 is decomposed.
