Chemical formula. Na 2 Se: Molar mass: 124.951 g·mol −1 Density: ... Sodium selenide is an inorganic compound of sodium and selenium with the chemical formula Na 2 Se.
Sodium hydroselenide is an inorganic compound with the chemical formula Na Se H. It is a salt of hydrogen selenide. It consist of sodium cations Na + and hydroselenide anions − SeH. Each unit consists of one sodium, one selenium, and one hydrogen atom. Sodium hydroselenide is a selenium analog of sodium hydroxide NaOH.
Sample of cadmium selenide, a pigment. The parent inorganic selenide is hydrogen selenide (H 2 Se). It is a colorless, malodorous, toxic gas. It dissolves in aqueous solution, to give the hydrogenselenide or biselenide ion HSe −. At higher pH, selenide forms. Solutions of hydrogen selenide and selenide are oxidized by air to give elemental ...
A hydroselenide (or biselenide or selanide) is an ion or chemical compound containing the [SeH] − ion. The radical HSe is a pseudohalogen.Hydroselenide can be a ligand in transition metal complexes where it can be attached to a single atom, or bridge two atoms.
Sodium selenide sodium biselenite: ... Sodium selenite is the inorganic compound with the formula Na 2 SeO 3.
In presence of a β-hydrogen, a selenide will give an elimination reaction after oxidation, to leave behind an alkene and a SeO-selenoperoxol. The SeO-selenoperoxol is highly reactive and is not isolated as such. In the elimination reaction, all five participating reaction centers are coplanar and, therefore, the reaction stereochemistry is syn.
Sodium selenate is the inorganic compound with the formula Na 2 SeO 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.
Sodium hydrogen selenite. Sodium hydrogen selenite is an inorganic chemical consisting of a ratio of one hydrogen, one sodium, three oxygen, and one selenium atom. It is the sodium salt of the conjugate base of selenous acid. This compound finds therapeutic application for providing the essential trace element selenium.
