Sodium metabisulfite has strong reducibility

Fire protection measures of sodium metabisulfite

　　Hazardous characteristics: strong reduction. Contact with strong oxidants such as chromic anhydride, chlorate and potassium permanganate can cause a strong reaction, causing combustion or explosion. Hazardous combustion products: sulfides. Fire extinguishing method: Firefighters must wear full-body fireproof and anti-virus suits and extinguish the fire in the upwind. When extinguishing the fire, move the container from the fire site to an open place as much as possible.

Emergency treatment of sodium metabisulfite leakage

　　Emergency treatment: Isolate the leaked contaminated area and restrict access. It is recommended that emergency personnel wear dust masks (full face masks) and anti-virus clothing. Avoid dust, sweep up carefully, transfer to a safe place in a bag. If there is a large amount of leakage, cover with plastic cloth or canvas. Collect and recycle or transport to waste disposal site for disposal.

Sodium metabisulfite pharmaceutical reducing agent and sulfonating agent

Sodium metabisulfite, where S is +4, which means it has antioxidant function

Sodium sulfate is an industrial salt. It is an incidental salt produced by other products produced by general factories. It is toxic, and sodium metabisulfite should be a salt that can be used by both. Phosphate is also oxidizing.

Sodium metabisulfite is used as a mordant for printing and dyeing, a dechlorinating agent after fabric bleaching; a reducing agent and a sulfonating agent for medicine; a bleaching agent for bamboo and paper fiber; a mineral processing agent for non-ferrous metals; wastewater treatment; rubber coagulant.
