  • Chemical Properties
    • white powder

  • General Description
    • White crystals or crystalline powder. Slight sulfurous odor. Specific gravity 1.48. Strong irritant to skin and tissue.

  • Air & Water Reactions
    • Water soluble.

  • Reactivity Profile

    Sodium bisulfite is a reducing agent. Emits highly toxic gaseous sulfur dioxide gas when heated to decomposition or on contact with mineral acids [Sax, 9th ed., 1996, p. 2949].

  • Health Hazard

    Powder is irritating to eyes, nose, and throat and can irritate skin. Ingestion may cause irritation of stomach. Very large doses cause violent colic, diarrhea, depression, and death.

  • Fire Hazard

    Flammable/combustible material. May ignite on contact with moist air or moisture. May burn rapidly with flare-burning effect. Some react vigorously or explosively on contact with water. Some may decompose explosively when heated or involved in a fire. May re-ignite after fire is extinguished. Runoff may create fire or explosion hazard. Containers may explode when heated.
