Air & Water Reactions
Soluble in water forming weakly acidic solutions.Reactivity Profile
Acidic salts, such as arsenic acid, sodium salt , are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.Health Hazard
(Non-Specific -- Arsenic) High mortality rate due to acute poisoning usually within 48 hours.Fire Hazard
When heated to decomposition, arsenic acid, sodium salt emits toxic fumes of arsenic.Safety Profile
Confirmed human carcinogen with experimental tumorigenic data. Poison by ingestion, intravenous, and intraperitoneal routes. An experimental teratogen. Other experimental reproductive effects. Mutation data reported. When heated to decomposition it emits toxic fumes of As and Na2O. See also ARSENIC COMPOUNDS.Check Digit Verification of cas no
The CAS Registry Mumber 7631-89-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,3 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.Calculate Digit Verification of CAS Registry Number 7631-89:
(6*7)+(5*6)+(4*3)+(3*1)+(2*8)+(1*9)=112
112 % 10 = 2
So 7631-89-2 is a valid CAS Registry Number.
