Characteristics-
PSA:
82.4
XLogP3:-4
Appearance:Sodium sulfite is a white odorless powder. Density 2.633 g / cm3. Moderately toxic. Sinks in water and dissolves slowly. Also transported as a heptahydrate Na2SO3.7H2O.
Density:2.63 g/cm3
Melting Point:>500°C
Boiling Point:Decomposes (NTP, 1992)
Refractive Index:1.484
Water Solubility:H2O: 23 g/100 mL (20 ºC)
Storage Conditions:Sodium sulfite should be stored in a well-closed container in a cool, dry, place. In solution, sodium sulfite is slowly oxidized to sulfate by dissolved oxygen; strong acids lead to formation of sulfurous acid/ sulfur dioxide. On heating, sodium sulfite decomposes liberating sulfur oxides.
Vapor Pressure:Negligible (NTP, 1992)
Toxicity:Non-toxic
Odor:Odorless
Taste:Saline, sulfurous taste
PH:8,5-11,5 (anhydrous: 10 % solution; heptahydrate: 20 % solution)
Experimental Properties:Density: 1.539. MP: decomposes; loses 7 H2O at 150 °C /Sodium sulfite heptahydrate/|Efflorescent crystals. Unstable, oxidizing in air to sulfate. Soluble in 1.6 parts water, about 30 parts glycerol; sparingly soluble in alcohol. Aqueous solution is alkaline and dissolves sulfur; pH approximately 9 /Sodium sulfite heptahydrate/
Air and Water Reactions:Soluble in water. Reacts with hot water, steam or acids to produce corrosive material.
Reactive Group:Sulfite and Thiosulfate Salts
Reactivity Alerts:Strong Reducing Agent
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].
Autoignition Temperature:Not flammable (USCG, 1999)
