Product Description

Sodium bisulfite (or sodium bisulphite, sodium hydrogen sulfite) is a chemical mixture with the approximate chemical formula NaHSO₃. Sodium bisulfite in fact is not a real compound,^[2] but a mixture of salts that dissolve in water to give solutions composed of sodium and bisulfite ions. It appears in form of white or yellowish-white crystals with an odor of sulfur dioxide.

Versatile Applications Across Industries

Sodium bisulphite's adaptability makes it valuable across a wide variety of sectors. It is used as a reducing agent in chemical synthesis, an antioxidant and preservative in the food industry, and helps in water purification processes by removing excess chlorine. Textile and pulp & paper industries also employ it for specific treatment steps that enhance product quality and stability.

Safe Storage and Handling Guidelines

For optimum stability, store sodium bisulphite in tightly sealed containers away from strong acids and oxidizers. Keep it in a cool, dry place to prevent decomposition and an unwanted release of sulfur dioxide gas. The substance is non-hazardous for transport, reducing related regulatory concerns during shipping and distribution.

Quality and Purity Assurance

Our sodium bisulphite boasts a minimum purity of 99% with heavy metal content below 0.001%, ensuring it meets rigorous laboratory-grade specifications. Each batch is available in customizable packaging, and the product's compliance with CAS No. 7631-90-5 and EC Number 231-548-0 makes it a reliable choice for researchers and industry professionals alike.

FAQ's of sodium bisulphite:

Q: How is sodium bisulphite typically used in water treatment and chemical processes?

A: Sodium bisulphite acts as a dechlorinating and reducing agent in water treatment plants, effectively removing excess chlorine. In chemical synthesis, it's used to reduce or react with certain compounds, making it indispensable in laboratory and industrial processes.

Q: What precautions should be taken when storing and handling sodium bisulphite?

A: It should be stored in a tightly closed container within a cool, dry area, away from strong acids and oxidizing agents. This prevents premature decomposition and limits the release of sulfur dioxide gas, ensuring both safety and product longevity.

Q: When does sodium bisulphite decompose, and what are the main decomposition products?

A: Sodium bisulphite decomposes at around 150C, releasing sulfur dioxide gas as the primary decomposition product. It does not have a boiling point since it breaks down before boiling.

Q: Where can sodium bisulphite be applied besides the laboratory setting?

A: Beyond laboratories, sodium bisulphite is widely used in the textile and pulp & paper industries for processing and preservation. It also serves as a food preservative, antioxidant, and in water treatment facilities for chlorine removal.

Q: What packaging and customization options are available for sodium bisulphite supply?

A: Sodium bisulphite is supplied in HDPE bags and drums, with custom packaging sizes available upon request. This ensures compatibility with specific industry needs and storage requirements.

Q: What distinct benefits does laboratory-grade sodium bisulphite offer?

A: Laboratory-grade sodium bisulphite ensures high purity (99%) with minimal heavy metal contamination (<0.001%), providing reliable results in sensitive applications. Its stringent quality control makes it suitable for scientific, industrial, and food-grade uses alike.
