Sodium selenite is the inorganic compound with the formula Na 2 SeO 3. This salt is a colourless solid. The pink coloured pentahydrate Na 2 SeO 3 (H 2 O) 5 is the most common water-soluble selenium compound.
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 ...
Selenite, satin spar, desert rose, and gypsum flower are crystal habit varieties of the mineral gypsum.. All varieties of gypsum, including selenite and alabaster, are composed of calcium sulfate dihydrate (meaning that it has two molecules of water), with the chemical formula CaSO 4 ·2H 2 O. Selenite contains no selenium, the similar names both derive from Greek selḗnē (σελήνη 'Moon').
Salts of selenous acid are called selenites. 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.
A selenate selenite is a chemical compound or salt that contains selenite and selenate anions (SeO 3 2-and SeO 4 2-). These are mixed anion compounds . Some have third anions.
Gypsum occurs in nature as flattened and often twinned crystals, and transparent, cleavable masses called selenite. Selenite contains no significant selenium; rather, both substances were named for the ancient Greek word for the Moon. Selenite may also occur in a silky, fibrous form, in which case it is commonly called "satin spar".
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.
