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 salts can be prepared by neutralizing solutions of selenous acid, which is generated by dissolving selenium dioxide in water. The process proceeds via the hydrogenselenite ion, HSeO − 3. Most selenite salts can be formed by heating the metal oxide with selenium dioxide, e.g.: Na 2 O + SeO 2 → Na 2 SeO 3
A bath salt tablet shaped like a seashell. Some bath salts act as water softeners and change the way soap rinses. High concentrations of salts increase the density of the water and increase buoyancy, which makes the body feel lighter in the bath. Very high concentrations of salts in water are used in many isolation tank therapies. Isolation ...

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.
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').
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".
