Sodium selenite is the inorganic compound with the formula Na2SeO3. This salt is a colourless solid. The pentahydrate Na2SeO3(H2O)5 is the most common water-soluble selenium compound.Sodium selenite usually is prepared by the reaction of selenium dioxide with sodium hydroxide:
SeO2 + 2 NaOH → Na2SeO3 + H2O
The hydrate converts to the anhydrous salt upon heating to 40 °C.
Akin to the related salt sodium sulfite, Na2SeO3 features a pyramidal dianion SeO32−.[2] Oxidation of this anion gives sodium selenate, Na2SeO4.

1. Sodium Selenite is a component of glutathione peroxidase, which maintains the function of cell membranes through oxidation and increases the production of endogenous antioxidants with the lipid nature of proteins. Participate in the conversion of energy, affect metabolism, and play an extremely important role in the emulsification and absorption of fat and the absorption of multiple vitamins. At the same time, it also participates in the synthesis of coenzyme A and coenzyme Q, and affects the functions of other biological enzyme systems. It has an impact on amino acid metabolism, protein synthesis, carbohydrate metabolism, and biological oxidation. The lack of selenium in the body of livestock and poultry will seriously affect the growth and reproduction of livestock and poultry. Alkaloid test. Seed germination test. Remove the green color when making glass. Color glaze preparation.
2. Sodium selenite is used in feed as a supplementary selenium element fortifier.
3. Sodium Selenite is used as a nutrient fortifier and feed additive
