Iron(III) selenite is an inorganic compound with the chemical formula Fe 2 (SeO 3) 3. It exists anhydrous form and as various hydrates. It exists anhydrous form and as various hydrates. The heptahydrate is produced by the reaction of ferric chloride and selenous acid (or sodium selenite ) at a pH of 1.05. [ 3 ]
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').
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 ...

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.
The Dendra panoply or Dendra armour is an example of Mycenaean-era panoply (full-body armor) made of bronze plates uncovered in the village of Dendra in the Argolid, Greece. It is currently on display at the Archaeological Museum of Nafplion .
Boron compounds are used as a reinforcing agent in order to harden metals for use in military tanks and armor. Boron is used extensively for fire retardant materials. Boron is an essential element for plant growth and is frequently used as a fertilizer, however in large concentrations boron can be toxic, and therefore boron is a common ...
Silver selenite is formed during the recovery of selenium from copper anode slimes when they are subjected to oxidative roasting, causing some silver selenide to be converted to the selenite. It can also be prepared by a precipitation reaction between silver nitrate and sodium selenite: [2]
