Sodium metabisulfite or sodium is an inorganic compound of chemical formula Na2S2O5. The substance is sometimes referred to as disodium metabisulfite. It is used as a disinfectant, antioxidant, and preservative agent.
Applications:
- It is used as a preservative in the starch and food industry to control melanosis (black spot) in shrimp; for fermentation in the wine industry; as an antichlor in the chemical industry and as a redox catalyst in the acrylic fibre industry.
- The product is also used as a reducing agent in the purification of aldehydes and ketones; in the manufacture of sulphonated oil and resin; for detoxification of cyanide in gold ore processing plants and in the manufacture of photographic chemicals.
- Sodium Metabisulphite's acidic and preservative properties also make it an effective substitute for sodium bisulfite, a chemical which is used in traditional darkroom photography.
- Also, Sodium Metabisulphite is used as a bleaching agent in pulp and textile manufacture, as well as a reducing agent in pharmaceuticals. It is also a known preservative in cosmetics.
- The chemical, in concentrated form, has also been used in landscape gardening as a tree stump remover, as it disintegrates the lignin -- chemicals in plant cell walls -- in the tree stumps, making them easier to remove.
