    Experimental Properties:

    Strong reducing agent; also available in liquid form|Decomposes violently when heated to 190 °C and emits toxic fumes of SOx and Na2O.

    Air and Water Reactions:

    Sodium dithionite is a combustible solid which slowly decomposes when in contact with water or water vapor, forming thiosulfates and bisulfites. This reaction evolves heat, which can further accelerate the reaction or cause surrounding materials to burn. If the mixture is confined, the decomposition reaction can result in pressurization of the container which may then rupture forcefully. Upon standing in air it slowly oxidizes, generating toxic sulfur dioxide gas. (NFPA, 2010)

    Reactive Group:

    Anhydrides

    Reactivity Alerts:

    Strong Reducing Agent
