General Description
Colorless rhombic crystals. Used as an insecticide in some horticultural applications.
Reactivity Profile
SODIUM SELENATE(13410-01-0) 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
Air & Water Reactions
Water soluble.
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.
Chemical Properties
White crystalline powder
Definition
ChEBI: An inorganic sodium salt having selenate as the counterion.
Purification Methods
Crystallise sodium selenate from hot water. [Fehér in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 433 1963].
Toxics Screening Level
The ITSL for selenium and inorganic selenium compounds (selenic acid) is 2 μg/m3 based on an 8-hour averaging time.
