Product Description
Product name:Sodium Sulfite Anhydrous
Chemical Formula:Na2SO3
Cas:7757-83-7
Description:
Industrial grade sodium sulfite (Na2SO3) holds significance as a crucial inorganic chemical product. It presents itself in the form of white crystals or powder and demonstrates high solubility in water, resulting in an alkaline aqueous solution.
Regarding its chemical characteristics, sodium sulfite possesses a notably strong reducing property. The sulfur element within sodium sulfite exhibits a valence state of +4, which empowers it to engage in reactions with a multitude of oxidizing agents.

Application
In both tap water treatment procedures and industrial circulating water systems, there is a likelihood of the presence of residuals in the water. These residuals have the potential to inflict harm upon aquatic organisms and certain water-utilizing equipment. However, sodium sulfite is capable of efficiently eliminating such residuals.
Within the context of the pulping stage in the paper manufacturing industry, sodium sulfite serves as a frequently employed additive in the cooking process. When it comes to chemical pulping techniques, notably the sulfate and sulfite processes, sodium sulfite plays an active role by taking part in the chemical reactions. Through its reaction with lignin, it facilitates the separation of lignin from plant fibers, consequently leading to the acquisition of cellulose pulp that possesses a comparatively high level of purity.
Sodium sulfite is also capable of averting the oxidation and subsequent color alteration of printed and dyed fabrics during their post-processing or storage periods. Fabrics are prone to coming into contact with atmospheric oxygen and subsequently undergoing oxidation reactions, which result in the fading or discoloration of their colors. Functioning as an antioxidant, sodium sulfite has the ability to chemically interact with oxygen and consume it, thus safeguarding the color integrity of the fabrics.
