Supply High quality ,low price and high purity of Sodium metabisulfite

Product Name: Sodium metabisulfite

CAS No.: 7681-57-4

Molecular weight: 190.10

Appearance: White crystalline powder, free from extraneous matter with a faint odour of sulphur dioxide gass.
 

Sodium metabisulfite is a white or yellow crystalline powder or a small crystal with a strong SO2 odor. The specific gravity is 1.4. It dissolves in water and the aqueous solution is acidic. When it comes into contact with strong acid, SO2 is released and the corresponding salt is generated. If it is left in the air for a long time, it is oxidized. As Na2S2O6, so the product can not exist for a long time. Above 150 degrees Celsius, SO2 is decomposed.

Synonyms: disodiummetabisulfite; disodiumpyrosulphite; fertisilo; metabisulfitedesodium; Sodiummetabisufite; sodiummetabisulfite(na2-s2o5); sodiumpyrosulfite(na2s2o5); Sodium dissulfite; Sodium disulphite; Sodium pyrosulphite

Application:

Used as a food preservative. It is a slight hazy solution free from inappropriate impurities. These sulphites are available in white and faint cream crystalline free flowing powder and are widely used in photographic chemical and preservative chemical.Used in medicine when producing chloroform,solasulfone and methnylal;used as coagulant in rubber industry; used as dechlorided agent or assistants in printing and dyeing industry; used to improve leather properties in leather industry; used as developing agent in photosensitivity industry; used when producing hydroxyl geranial, hydrochloric hydroxylamine in chemical industry; used as bleaching agent, antiseptics,  antioxidant, ect.in food industry.
