アルソン酸/カリウム,(1:x) 化学特性,用途語,生産方法
化学的特性
White powder. Hygroscopic; decom-
poses slowly in air. Variable composition. Keep
well stoppered. Soluble in water; slightly soluble
in alcohol.
使用
Reducing agent in silvering mirrors.
一般的な説明
A white powder. Toxic by ingestion and by inhalation.
空気と水の反応
Soluble in water. Decomposes slowly in air.
反応プロフィール
Salts, basic, such as POTASSIUM 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. Fire may produce irritating or poisonous gases. Unstable. Avoid aeration. [EPA, 1998].
危険性
Toxic by ingestion and inhalation, strong
irritant.
健康ハザード
Very toxic: probable oral lethal dose in humans is 50-500 mg/kg, or between 1 teaspoonful and one ounce for a 150-lb. adult. It is a skin irritant and allergen. Acute allergic reactions to arsenic compounds are fairly common.
火災危険
Fire may produce irritating or poisonous gases. Unstable. Avoid aeration.
安全性プロファイル
Confirmed human
carcinogen producing skin and liver tumors.
Poison by ingestion, skin contact,
subcutaneous, and intravenous routes.
Human mutation data reported. Human
systemic effects: dermatitis, liver changes.
When heated to decomposition it emits
toxic fumes of As and K2O. Used in
veterinary mehcine and for chronic dermatitis in humans. See also ARSENIC
COMPOUNDS.
