Sodium selenate Chemical Properties,Uses,Production
Chemical Properties
White crystalline powder
Uses
Sodium selenate has been used as an inorganic source of selenium:
- to study its effect on the immune response and disease resistance of prawn
- to study its antioxidant defense and in glucose homeostasis in streptozotocin-induced diabetes
- as standard in enzymatic hydrolysis
Uses
Sodium selenate is used in glass industry, and produces red hue in glass. It acts as a decoloring agent in glass production. Combined with ferrous oxides, it produces colorless glass. Appropriate preparation of sodium selenate is used in multivitamins.
Uses
Reagent, insecticide for nonedible plants.
Definition
ChEBI: An inorganic sodium salt having selenate as the counterion.
General Description
Colorless rhombic crystals. Used as an insecticide in some horticultural applications.
Air & Water Reactions
Water soluble.
Reactivity Profile
Sodium selenate has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive. Light sensitive
Hazard
Toxic by ingestion.
Health Hazard
Causes damage to liver and kidneys. Resembles arsenic in its effects.
Fire Hazard
Fire may produce irritating or poisonous gas. Emits toxic selenium and sodium oxide fumes when heated to decomposition. Avoid decomposing heat.
Safety Profile
Poison by ingestion, intravenous, subcutaneous, and intraperitoneal routes. Questionablecarcinogen with experimental carcinogenic and teratogenic data. Human systemic effects by ingestion: EKG changes, hypermotility, diarrhea, and liver impairment. Experimental reproductive effects. Effects sdar to those of arsenic. Mutation data reported. A pesticide. When heated to decomposition it emits toxic fumes of Se and NanO. See also SELENIUM COMPOUNDS and ARSENIC COMPOUNDS.
Purification Methods
Crystallise sodium selenate from hot water. [Fehér in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 433 1963].
