How is selenate formed?
Sodium selenate is produced by oxidation of selenium, first with nitric acid, producing selenous acid. The selenous acid is neutralized to form sodium selenite. The sodium selenite is oxidized in a basic medium hydrogen peroxide to form a selenate, which is then spray-dried. Na2SeO3 + H2O2 → Na2SeO4 + H2O.

What is the charge of selenate?
+6
Selenate. Selenate is a polyanion made up of Se and oxygen. The Se ion has a charge of +6 and is bound to four oxygen ions, forming a polyanion with a net charge of (-2).
Is Selenate a base?
Selenate is a divalent inorganic anion obtained by removal of both protons from selenic acid. It has a role as a human metabolite. It is a selenium oxoanion and a divalent inorganic anion. It is a conjugate base of a hydrogenselenate.
What is se2cl3?
Selenium monochloride is an inorganic compound with the formula Se2Cl2. It exists in chemical equilibrium with SeCl2, SeCl4, chlorine, and elemental selenium. Selenium monochloride is mainly used as a reagent for the synthesis of Se-containing compounds.

Is sodium selenate the same as selenite?
Chosen for its selenium content and high solubility, sodium selenate is a common ingredient in over-the-counter vitamin supplements. Selenium is a trace essential element. Sodium selenate and selenite are also common in premix animal feed. Neither compound has demonstrated a difference in the amount of selenium absorbed.
Is decahydrate the same as sodium selenate?
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.
