| 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. |
