    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)
