10124-50-2 Usage
Chemical Properties
White powder. Hygroscopic; decom-
poses slowly in air. Variable composition. Keep
well stoppered. Soluble in water; slightly soluble
in alcohol.
Uses
Reducing agent in silvering mirrors.
General Description
A white powder. Toxic by ingestion and by inhalation.
Air & Water Reactions
Soluble in water. Decomposes slowly in air.
Reactivity Profile
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].
Hazard
Toxic by ingestion and inhalation, strong
irritant.
Health Hazard
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.
Fire Hazard
Fire may produce irritating or poisonous gases. Unstable. Avoid aeration.
Safety Profile
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.
Check Digit Verification of cas no
The CAS Registry Mumber 10124-50-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,2 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 10124-50:
(7*1)+(6*0)+(5*1)+(4*2)+(3*4)+(2*5)+(1*0)=42
42 % 10 = 2
So 10124-50-2 is a valid CAS Registry Number.
