Sodium m-arsenite Chemical Properties,Usage,Production

Chemical Properties white granular crystals General Description A white or grayish-white powder. Denser than water. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion, inhalation and skin absorption. Air & Water Reactions Soluble in water. Slowly converted in solution to arsenates by atmospheric oxygen; in dry state Sodium m-arsenite is decomposed by carbon dioxide. [EPA, 1998]. Reactivity Profile Salts, basic, such as SODIUM ARSENITE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Health Hazard Extremely toxic: probable oral lethal dose (human) 5-50 mg/kg, between 7 drops and one teaspoon for 70 kg person (150 lb.). Poisonous if swallowed or inhaled. Human suspected carcinogen. Fire Hazard Sodium m-arsenite may burn but does not ignite readily. When heated Sodium m-arsenite emits toxic fumes of arsenic and sodium oxide. Slowly converted in solution to arsenates by atmospheric oxygen; in dry state Sodium m-arsenite is decomposed by carbon dioxide.
