Sodium selenite

Description:
Sodium selenite is an inorganic compound with the formula Na2SeO3. It appears as a white or colorless crystalline solid and is highly soluble in water. This compound is a source of selenium, an essential trace element for various biological functions, including antioxidant activity and thyroid hormone metabolism. Sodium selenite is often used in laboratory settings for selenium supplementation and in the production of selenium-containing compounds. It exhibits both reducing and oxidizing properties, making it useful in various chemical reactions. However, it is important to handle sodium selenite with care, as it can be toxic in high doses and poses health risks if ingested or inhaled. In terms of its chemical behavior, sodium selenite can undergo oxidation to form selenate or reduction to elemental selenium under certain conditions. Its applications extend to agriculture, where it is used as a micronutrient in fertilizers, and in the pharmaceutical industry for its potential therapeutic effects.
