sodium sulfite anhydrous 7757-83-7

molecular formula : na2so3

molecule weight : 126.04

cas no .: 7757-83-7

appearance : white free flowing fine crystal or powder

sodium sulfite (sodium sulphite) is a soluble sodium salt of sulfurous acid (sulfite) with the chemical formula na2so3. it is a product of sulfur dioxide scrubbing, a part of the flue-gas desulfurization process. it is also used as a preservative to prevent dried fruit from discoloring, and for preserving meats, and is used in the same way as sodium thiosulfate to convert elemental halogens to their respective hydrohalic acids, in photography and for reducing chlorine levels in pools.

we use experienced technology for production. first,extract the chean gas of sulfur dioxide from the production part of sulfuric acid, mixture with food grade sodium carbonate,it comes out high quality sodium hydrogen sulfite. second,after chemical treatment of sodium hydrogen sulfite ,mixture with ionic membrane sodium hydroxide, generated sodium sulfite with water. after concentration, desiccation and crystallization,it comes out sodium sulfite anhydrous,then we packed up the products into the warehouse.

Sodium sulfite Structure
Sodium sulfite Usage And Synthesis
Description As a soluble sodium salt of sulfurous acid, Sodium sulfite (Na2SO3) shows blenching, de-sulfurizing and dechlorinating properties which is widely applied in various fields. It is primarily used in the pulp and papermaking industry due to its blenching activity. It can serve as a good additive to help preserve the fresh appearance of good products. Besides, sodium sulfite is a component in many pharmaceuticals, which is effective to maintain the potency and stability of drugs. It can also be applied for water treatment as an oxygen scavenger agent and applied in flue gas desulfurization and preservation of photo developer solutions, etc.
Chemical Properties white crystals or powder
Definition ChEBI: An inorganic sodium salt having sulfite as the counterion.
General Description White odorless powder. Density 2.633 g / cm3. Moderately toxic. Sinks in water and dissolves slowly. Also transported as a heptahydrate Na2SO3.7H2O.
Air & Water Reactions Soluble in water. Reacts with hot water, steam or acids to produce corrosive material.
Reactivity Profile Sodium sulfite is a reducing agent, particularly under basic conditions. Reacts with oxidizing agents such as peroxides, epoxides, oxoacids. Emits toxic fumes of sodium oxide and oxides of sulfur if heated to decomposition [Lewis, 3rd ed., 1993, p. 1174].
Health Hazard When ingested, solutions cause gastric irritation by the liberation of sulfurous acid. Because of rapid oxidation to sulfate, sulfites are well tolerated until large doses are reached; then violent colic and diarrhea, circulatory disturbances, central nervous depression, and death can occur.
Fire Hazard Literature sources indicate that Sodium sulfite is noncombustible.
