Sodium Sulfite Anhydrous

Description

Sodium Sulfite Anhydrous (Na₂SO₃)

Sodium Sulfite Anhydrous is the dehydrated form of sodium sulfite, a versatile inorganic compound valued for its reducing properties. It is a white to off-white crystalline powder, readily soluble in water. The anhydrous form offers advantages in terms of stability and concentration compared to the hydrated forms, making it a preferred choice when minimizing water content is crucial.

Key Uses:

Food Preservation: Used as a preservative (E221) in various food products to prevent oxidation, enzymatic browning, and microbial growth, thus extending shelf life and maintaining quality. It is particularly effective in preserving the color of dried fruits, preventing discoloration in processed meats, and acting as an antioxidant in certain beverages. It also helps to inhibit the growth of some microorganisms. Note: Some individuals are sensitive to sulfites, so labeling is important. The anhydrous form offers a higher concentration of active ingredient per unit weight.

Photography: A component of some photographic developing solutions. It acts as a preservative for the developing agent, preventing its premature oxidation and extending its lifespan. It also helps to control the rate of development.

Water Treatment: Used to remove dissolved oxygen from boiler feedwater, preventing corrosion of pipes and equipment. It reacts with dissolved oxygen to form sodium sulfate. It is also used to dechlorinate water, neutralizing the harmful effects of chlorine in industrial wastewater and other applications.

Textile Industry: Used in the textile industry as a reducing agent in various dyeing and bleaching processes. It can also be used to remove excess chlorine from fabrics after bleaching.

Chemical Industry: Employed in various chemical processes as a reducing agent. It is used in the production of certain chemicals and as a reagent in various chemical reactions.

Other Applications:

• Pulp and Paper Industry: Used in some pulping processes.
• Pharmaceuticals: Used in some pharmaceutical formulations.

Packaging: Available in various packaging options to suit your needs, including bags and supersacks.
