Chlorite (ClO2), a halite

A halite, also known as a halogenite,[1] is an oxyanion containing a halogen in a III oxidation state. It is the conjugate base of a halous acid. The known halites are chlorite, bromite, and iodite.

Uses

Halites can be used to generate the respective halogen dioxides via a one-electron oxidation:

5 NaClO2 + 4 HCl5 NaCl + [[Chlorine dioxide|4 Шаблон:Chem]] + 2 H2O
[[Bromite|Шаблон:Chem]] + HBrO3 + H+ → [[Bromine dioxide|2 Шаблон:Chem]] + H2O

This reaction in particular is used in bleach to generate chlorine dioxide.

Stability

Chlorites tend to decompose rapidly, some even explosively, upon heating.[2] A few bromites have been isolated, but no iodites have.[3]
