Sodium selenite Chemical Properties,Usage,Production

Chemical Properties
White to light beige crystals
Usage
Used in reducing carcinogenesis with potency greater than selenomethionene
General Description
A white colored crystalline solid. Soluble in water and more dense than water. Contact may irritate skin, eyes and mucous membranes. Toxic by ingestion, inhalation and skin absorption.
Air & Water Reactions
Soluble in water.
Reactivity Profile
Sodium selenite is incompatible with strong acids.
Health Hazard
Toxic by ingestion. In humans, a concentration of 5 ppm in food or 0.5 ppm in milk or water has been estimated to be dangerous. Elemental selenium has low acute systemic toxicity, but dust or fumes can cause serious irritation of the respiratory tract.
Fire Hazard
May burn but will not ignite readily. When heated to decomposition, may emit toxic fumes of selenium and sodium oxide. Stable in air.
