Sodium Hydrogen Sulfite
Product Details
Specifications provided
White crystal (content ≥96% )
(Scope of application reference ‘product usage’)
Sodium bisulfite is an acid salt of weak acid, bisulfite ions will be ionized, producing hydrogen ions and sulfite ions, while bisulfite ions will be hydrolyzed, producing sulfite and hydroxide ions, the degree of ionization of bisulfite ions is greater than the degree of hydrolysis, so sodium bisulfite solution is acidic.

Product Usage
Main use
1. Used for bleaching cotton fabric and organic matter. Printing and dyeing industry as a deoxidizing agent and bleaching agent, used in various cotton fabrics cooking, can prevent cotton fiber localization and affect the strength of the fiber, and improve the whiteness of the cooking;
2. As a catalyst, used to catalyze organic reactions;
3. Used as a reducing agent in the organic industry, can prevent the oxidation of semi-finished products during the reaction process;
4. As a gas consumable, it can absorb oxidants such as sulfate and ammonia in the gas;
5. Raw materials for the preparation of anhydrous ethanol;
6. Used in photographic reducing agent, photosensitive industrial developer;
7. Paper industry used as lignin removal agent;
8. Electronics industry for the manufacture of photoresistor;
9. Used as electroplating additive;
10. Used to treat all kinds of chromium-containing wastewater produced in the process of electroplating;
11. Used for decolorization and cleaning wastewater, so that organic substances and other polluting substances removal, is a method of sewage treatment;
12. Sodium bisulfite is mainly used as a reducing agent in RO reverse osmosis system to remove chlorine, ozone, rust and other substances that lead to membrane pollution and oxidation;
13. Food grade sodium bisulfite commonly used as bleach, preservative, antioxidant;
14. In agriculture, sodium bisulfite can occur in the body of the crop REDOX reaction, the release of sulfur dioxide and nitric oxide and other active substances, promote the growth and development of crops. In addition, it can also provide sulfur for crops, increase the nutrient content of crops, improve the quality and yield of crops, and improve the pH of the soil and improve the fertility of the soil.
