sodium sulfite usage and synthesis |
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. |
