SODIUM ARSENATE Chemical Properties,Uses,Production
Chemical Properties
Sodium arsenate is currently registered for use as ant bait. These baits are used in approximately 1% of US homes. Sodium arsenate is a pentavalent form of inorganic arsenic. It is a heptahydrate that normally exists as colorless crystals with no discernible odor. Sodium arsenate contains 24% arsenic.
Uses
Mordant and assist in dyeing and printing, other arsenates, germicide.
Definition
ChEBI: An inorganic sodium salt composed from sodium cations and arsenate dianions in a 2:1 ratio.
Preparation
Sodium arsenate is obtained by roasting a mixture of arsenic oxide with sodium carbon ate and sodium nitrate in the presence of air.In addition, this compound can be easily obtained by calcining sodium arsenate(III) in the pres ence of air.
Hazard
Toxic by ingestion and inhalation.
Health Hazard
Exposures to arsenic acid disodium salt cause adverse health effects. The symptoms of poisoning include, but are not limited to, cough, headache, sore throat, weakness, respiratory distress, labored breathing, irritation to the eyes, and skin, dermatitis, mucous membranes, the respiratory tract, and pigmentation disorders. Repeated or prolonged contact with arsenic acid disodium salt causes cardiovascular disorders affects the nervous system, neuropathy, and kidneys, resulting in severe gastroenteritis, loss of fl uids and electrolytes, kidney impairment, collapse, shock, and death.
Contact allergens
Arsenic salts are sensitizers, but most often irritants. They are used in copper or gold extraction, glass, feeds, weedkillers, insecticides, and ceramics. A recent case was reported in a crystal factory worker with positive patch tests to sodium arsenate.
Safety Profile
Confirmed human carcinogen. Poison by intraperitoneal route. Human mutation data reported. When heated to decomposition it emits toxic fumes of arsenic. See ARSENIC COMPOUNDS.
Potential Exposure
Sodium arsenate is used in dyeing and printing; making other arsenates; as a germicide; in dyeing with turkey-red oil.
storage
It is important to keep stored organic arsenic compounds in a cool, dry, well-ventilated area in tightly sealed containers and with proper labels and identifi cation. The storage containers of organic arsenic compounds should be protected from physical damage and stored separately from oxidizers such as perchlorates, peroxides, permanganates, chlorates, or nitrates, and strong acids such as hydrochloric, sulfuric, or nitric acid. Further, specifi c organic arsenic compounds must have separate storage requirements, which should be evaluated prior to storage.
Precautions
During handling and use of arsenic compounds, workers should use appropriate personal protective clothing and equipment. Users/workers must be careful during use, and maintain effective measures to prevent skin contact with organic arsenic compounds. The selection of the appropriate personal protective equipment (PPE), such as gloves, sleeves, and encapsulating suits should be based on the extent of the worker’s potential exposure to organic arsenic compounds. The users and the management should periodically evaluate and determine the effectiveness of the chemical-resistant clothing in preventing dermal contact and ensuring users’ safety.
