Sodium Metabisulfite Na2s2o5 Cas 7757-83-7 For Water Treatment

Sodium Metabisulfite CAS 7757-83-7 for with Water Treatment

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. Above 150 degrees Celsius, SO2 is decomposed.

Description:
White or light yellow crystal powder, a strong smell of sulfur dioxide,relative density is 1.4, easy to dissolve in water and glycerin, water solution. It has acidity,and its solubility will become large while raising the temperature and is less to dissolve in ethanol.
