Selenite (ion)

Selenite refers to the anion with the chemical formula Se O2−3. It is the oxyanion of selenium. It is the selenium analog of the sulfite ion, SO2−3. Thus selenite is pyramidal and selenium is assigned oxidation state +4. Selenite also refers to compounds that contains this ion, for example sodium selenite Na₂SeO₃ which is a common source of selenite.^[1] Selenite also refers to the esters of selenous acid, for example dimethyl selenite (CH₃)₂SeO₃.
