Sodium selenite is the inorganic compound with the formula Na 2 SeO 3. This salt is a colourless solid. ... Selenite (ion) Selenous acid; References
Selenite refers to the anion with the chemical formula Se O 2− 3. It is the oxyanion of selenium. It is the selenium analog of the sulfite ion, SO 2− 3. Thus selenite is pyramidal and selenium is assigned oxidation state +4. Selenite also refers to compounds that contains this ion, for example sodium selenite Na 2 SeO 3 which is a common ...
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.
These include silver selenite (Ag 2 SeO 3) and sodium selenite (Na 2 SeO 3). Hydrogen sulfide reacts with aqueous selenous acid to produce selenium disulfide: + + Selenium disulfide consists of 8-membered rings.
Selenite (ion), anion is a selenium oxoanion with the chemical formula SeO 3 2−. Selenous acid, the conjugate acid, with the formula H 2 SeO 3; Salts of this anion: Silver selenite, an inorganic compound of formula Ag 2 SeO 3; Sodium selenite, a salt, a colourless solid, and the most common water-soluble selenium compound
The selenate ion is SeO 2− 4. [1] Selenates are analogous to sulfates and have similar chemistry. They are highly soluble in aqueous solutions at ambient temperatures. [2] Unlike sulfate, selenate is a somewhat good oxidizer; it can be reduced to selenite or selenium. [3] In strongly acidic conditions, the hydrogen selenate ion, HSeO − 4 ...
Sodium selenite Sodium selenate ... Sodium selenide is an inorganic compound of sodium and ... This hydrolysis occurs because of the extreme basicity of the Se 2− ion.
Selenium occurs naturally in a number of inorganic forms, including selenide, selenate, and selenite, but these minerals are rare. The common mineral selenite is not a selenium mineral, and contains no selenite ion, but is rather a type of gypsum (calcium sulfate hydrate) named like selenium for the moon well before the discovery of selenium ...
