Product Overview
Sodium sulfite, anhydrous, 98% is a high-purity chemical compound widely recognized for its strong reducing and antioxidant properties. This fine, white crystalline powder is highly soluble in water, making it ideal for various laboratory applications where precise control over oxidation-reduction reactions is required. The anhydrous form ensures stability and long shelf life, minimizing moisture-related degradation. Its high purity level of 98% guarantees consistent performance in sensitive procedures, reducing the risk of contamination or unwanted side reactions. The compound acts as an effective oxygen scavenger, preventing oxidative damage in solutions and samples. Its versatility extends to applications requiring sulfur dioxide generation, as it readily decomposes under acidic conditions. The powder’s uniform particle size distribution ensures even dissolution and reaction kinetics. This laboratory-grade sodium sulfite is manufactured under strict quality controls to meet the demanding standards of research environments. Its non-hygroscopic nature in the anhydrous form makes it particularly suitable for long-term storage and repeated use in laboratory settings where moisture control is critical.
FAQs
1
What is the difference between anhydrous and hydrated sodium sulfite?
Anhydrous sodium sulfite contains no water molecules in its crystal structure, while the hydrated form typically contains seven water molecules per formula unit. The anhydrous form is more stable for long-term storage and provides higher purity in reactions. 2
Can this sodium sulfite be used for food preservation applications?
This product is laboratory-grade and not certified for food use. Food-grade sodium sulfite would require different purity standards and certifications that this product doesn’t possess. 3
What safety precautions should be taken when handling this chemical?
Always wear appropriate personal protective equipment including gloves, goggles, and lab coat. Work in a well-ventilated area or fume hood, as the powder can irritate respiratory system when inhaled. 4
How should this product be stored to maintain its purity?
Store in a tightly sealed container in a cool, dry place away from moisture and incompatible substances. Keep the container properly labeled and separate from acids and oxidizing agents. 5
What is the typical shelf life of anhydrous sodium sulfite?
When stored properly in its original, unopened container, this product typically maintains its specified purity for 2-3 years from the date of manufacture.
