Description
White, slightly hygroscopic crystals. Sodium chlorite is a powerful oxidizing agent. A dilute aqueous solution produces chlorous acid which is used as a mild Bleaching agent for textiles. Sodium chlorite is also used for the dilignification of paper pulp.
Risks
- Very strong oxidizer.
- Fire and explosion hazard in contact with organic materials.
- Highly corrosive to tissues.
- Causes corrosion and burns.
- ThermoFisher: SDS
