Chlorite (group of substances)

from Wikipedia, the free encyclopedia

As Chlorite salts are referred to the chlorous acid HClO 2 . In the chlorite anion [ClO 2 ] - , chlorine has an oxidation number of +3. In this oxidation state, chlorine or chlorite is a strong oxidizing agent that decomposes easily.

Chlorites are in the art by introducing chlorine dioxide (ClO 2 ) in sodium hydroxide - hydrogen peroxide - Solutions prepared.

The most important of these is sodium chlorite , a white crystalline salt. It is stable in its pure form and can be handled safely in solution. However, it is explosive when mixed with flammable substances. The light yellow chlorites of silver and lead, which are sparingly soluble in water , are per se explosive and may only be isolated in their pure form with appropriate protective measures.

Chlorites are used as bleaching agents for textiles. The ClO 2 , which is released during acidification, bleaches fiber-friendly.
