Sodium sulfite Chemical Properties,Usage,Production

Chemical Properties white crystals or powder 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.
