What properties does sodium bisulfite show

Sodium bisulfite is a common compound. The acidity of sulfurous acid is stronger than that of methyl bisulfate. It has a wide range of uses in various fields. For example, it is often used in cotton fabrics and bleaching of some organic matter. It is often used as a reducing agent in dyes and chemical synthesis. In the pharmaceutical industry, it is an intermediate in the production of analgin. It is often used in food bleaching agents, preservatives and antioxidants.

The functions of sodium bisulfite are:

1. Used for bleaching cotton fabrics and organic matter. 2. Used as reducing agent in dye, papermaking, leather making, chemical synthesis and other industries.

3. The pharmaceutical industry uses it as an intermediate for the production of analgin and aminopyrine.

4. Food-grade products are used as bleaching agents, preservatives, and antioxidants.

5. Used for the treatment of chromium-containing wastewater and as an electroplating additive.

Shipping Methods

1. Transportation precautions: The packaging should be complete and the loading should be secure during shipment. During transportation, ensure that the container does not leak, collapse, fall or be damaged. It is strictly prohibited to mix and transport with oxidants, acids, alkalis, edible chemicals, etc. During transportation, the transport vehicle should be equipped with leakage emergency treatment equipment. During transportation, it should be protected from exposure to sunlight, rain and high temperature. When transporting by road, the vehicles must follow the prescribed routes and avoid stopping in residential areas or densely populated areas;

2. Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. The package is sealed. It should be stored separately from oxidants, acids and alkalis and should not be mixed. It should not be stored for a long time to avoid spoilage. The storage area should be equipped with appropriate materials to contain leaks; 3. Packaging precautions: small-opening aluminum barrels; ordinary wooden boxes for ampoules; ordinary wooden boxes for threaded glass bottles, iron-capped glass bottles, plastic bottles or metal barrels (cans).

Common rumors

Rumor: Potassium chlorate and sodium bisulfite undergo redox reaction to produce Cl- Refutation: Potassium chlorate and sodium bisulfite react to form chlorine dioxide: 2ClO3-+HSO3-+H+=2ClO2+SO42-+H2O. The above rumor is not only wrong, but more seriously, if imitated it may cause an explosion.
