| 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
