Product Overview
Sodium sulfite anhydrous LR is a high-purity, white crystalline powder widely used as a reducing agent in laboratory applications. With a minimum assay of 97%, this laboratory reagent grade chemical ensures reliable performance in redox reactions, dechlorination processes, and as an antioxidant in various formulations. Its anhydrous form guarantees stability and extended shelf life, making it a preferred choice for experiments requiring consistent results. The compound is highly soluble in water, forming a slightly alkaline solution, which enhances its versatility in different chemical processes. Sodium sulfite is particularly valued for its ability to neutralize chlorine and other oxidizing agents, making it indispensable in water treatment simulations and analytical chemistry. Store in a cool, dry place in a tightly sealed container to prevent moisture absorption and maintain purity. This product is rigorously tested to meet LR grade standards, ensuring minimal impurities and maximum efficiency in critical applications.
FAQs
1. What is the solubility of sodium sulfite anhydrous in water?
Sodium sulfite anhydrous is highly soluble in water, with a solubility of approximately 260 g/L at 20°C, forming a clear, colorless solution.
2. Can this product be used for dechlorination in water treatment experiments?
Yes, sodium sulfite anhydrous LR is commonly used for dechlorination due to its strong reducing properties that effectively neutralize chlorine.
3. What precautions should be taken while handling this chemical?
Wear protective gloves, goggles, and a lab coat. Avoid inhalation of dust and ensure proper ventilation, as it may release sulfur dioxide upon reaction with acids.
4. How does the LR grade differ from AR or analytical grade?
LR grade is suitable for general laboratory use with slightly lower purity than AR grade, which is designed for precise analytical applications requiring minimal impurities.
5. Is this product compatible with acidic solutions?
No, sodium sulfite reacts with acids to release sulfur dioxide gas, so it should be used cautiously in neutral or alkaline conditions.
