Sulphur dioxide oxidation number
Can act as an oxidizing agent. Used to manufacture chemicals, in paper pulping, in metal and food processing. Reacts exothermically with bases such as amines, amides, metal oxides, and hydroxides.
Containers may explode in heat of fire or they may rupture and release irritating toxic sulfur dioxide. Avoid ammonia, monocesium or monopotassium acetylide; dicesium monoxide; iron II oxide; tin oxide; lead IV oxide; chromium; manganese; molten sodium, powder aluminum and rubidium.
Special Warning from DuPont: Tychem® and Tyvek® fabrics should not be used around heat, flames, sparks or in potentially flammable or explosive environments. EPA, It may cause death or permanent injury after very short exposure to small quantities. Ethylene oxide and SO2 can react violently in pyridine solution with pressurization if ethylene oxide is in excess Nolan, , Case History The Response Recommendation fields include isolation and evacuation distances, as well as recommendations for firefighting, non-fire response, protective clothing, and first aid.
Sulfur dioxide has explosive properties when it comes in contact with sodium hydride; potassium chlorate at elevated temperatures; ethanol; ether; zinc ethylsulfurinate at very cool temperatures C ; fluorine; chlorine trifluoride and chlorates.
If the water is hot an explosion may occur. Frequently used as a reducing agent although it is not a powerful one. Pressures may build to dangerous levels if the liquid contacts water in a closed container [Handling Chemicals Safely ]. A colorless gas with a choking or suffocating odor. Reacts explosively with fluorine [Mellor ]. It will react with water or steam to produce toxic and corrosive fumes. Heavier than air.
ERG, Wear self-contained breathing apparatus and full protective clothing. Supports burning of manganese [Mellor ]. What is this information? Boiling point °C. Supports incandescent combustion of monocesium acetylide, monopotassium acetylide, cesium oxide, iron II oxide, tin oxide, and lead oxide [Mellor].

Contact between the liquid and water may result in vigorous or violent boiling and extremely rapid vaporization. Under prolonged exposure to fire or heat the containers may rupture violently and rocket. Readily liquefied by compression. Supports combustion of powdered aluminum [Mellor ]. Hazardous polymerization may not occur. It is an eye and respiratory tract irritant. Very toxic by inhalation and may irritate the eyes and mucous membranes.
Flammability 0 Will not burn under typical fire conditions. The Hazard fields include special hazard alerts air and water reactions, fire hazards, health hazards, a reactivity profile, and details about reactive groups assignments and potentially incompatible absorbents.
Acts as a reducing bleach to decolorize many materials. Stay away from ends of tanks. Dissolves in water to form sulfurous acid, a corrosive liquid. Persons with asthma, subnormal pulmonary functions or cardiovascular disease are at a greater risk.
When the liquid is heated it may release irritating, toxic sulfur dioxide gas. Department of Transportation hazard labels, and a general description of the chemical. Move container from fire area. Instability 0 Normally stable, even under fire conditions. Moist sulfur dioxide is very corrosive due to the slow formation of sulfuric acid [Handling Chemicals Safely p.
