Product Description
Sodium Metabisulfite Powder 96.5% Min Na2S2O5 White Powder CAS:7681-57-4
1.Description:
Sodium metabisulfite is white or yellow crystalline powder or small crystals, with a strong smell of SO2, specific gravity 1.4, soluble in water, aqueous solution is acidic, and strong acid contact release SO2 and generate the corresponding salts, a long time in the air, oxidation into Na2S2O6, so the product can not survive. Above 150 degrees Celsius, SO2 is broken down.
2.Applications:
Insurance powder, sulfadimethylpyrimidine, anemone, caprolactam, etc.
Ingredients for fixing agents in the photographic industry.

4.Feature Advantages:
Soluble in glycerol, slightly soluble in ethanol.
The relative density is 1.4. Soluble in water soluble in glycerol, slightly soluble in ethanol.
It is easily decomposed by moisture and easily oxidized into sodium sulfate when exposed to air.
Contact with strong acids releases sulfur dioxide and forms the corresponding salts. Decompose when heated to 150℃.
