SODIUM METABISULFITE is a white crystalline or powder solid with a slight sulfur odor. Toxic by inhalation . Strongly irritates skin and tissue. Noncombustible, but may decompose to emit toxic oxide fumes of sulfur and sodium when heated to high temperature. A corrosive acid when mixed with water. Used as a food preservative and as a laboratory reagent.
Sodium metabisulfite or sodium pyrosulfite (IUPAC spelling; Br. E. sodium metabisulphite or sodium pyrosulphite) 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 preservativeagent.
Sodium Metabisulphite SM 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.
