Sodium selenate is the inorganic compound with the formula Na
₂SeO
₄. It exists as the anhydrous salt, the heptahydrate, and the decahydrate.^[1] These are white, water-soluble solids. The decahydrate is a common ingredient in multivitamins and livestock feed as a source of selenium. The anhydrous salt is used in the production of some glass. Although the selenates are much more toxic, many physical properties of sodium selenate and sodium sulfate are similar.^[2]
