What is chlorite ions?

Chlorite ions are negatively charged ions that are derived from chlorous acid. The chemical formula for chlorite ion is ClO2-. Chlorite ions have an octahedral structure with one chlorine atom at the center and two oxygen atoms bonded to it. A single negative charge balances the three atoms.

Chlorite ions are commonly used in water treatment to disinfect and sterilize water. They are also used in the manufacture of various chemical compounds, such as sodium chlorite and magnesium chlorite. Chlorite ions can be toxic if they are ingested in excessive amounts.

In addition to water treatment, chlorite ions are used in the pulp and paper industry as a bleaching agent. Chlorite ions are also used in the production of fireworks to create a green color. Chlorite ions have a melting point of 180˚C and are soluble in water and alcohol.
