Product Overview
Sodium sulfite anhydrous ARS ACS grade is a high-purity chemical compound widely used in laboratories for its strong reducing properties. This white, crystalline powder is highly soluble in water, forming a slightly alkaline solution. The ARS (Analytical Reagent Standard) and ACS (American Chemical Society) grades ensure exceptional purity, making it suitable for precise analytical applications. It acts as an effective oxygen scavenger, preventing oxidation in various processes. The anhydrous form guarantees stability and prolonged shelf life when stored under appropriate conditions. Its molecular formula, Na₂SO₃, reflects its composition of sodium, sulfur, and oxygen, contributing to its reactivity in redox reactions. The compound is non-toxic but should be handled with care to avoid inhalation or direct contact. Its versatility extends to applications requiring controlled reduction environments, making it a staple in chemical synthesis and preservation processes.
FAQs
1. What is the shelf life of sodium sulfite anhydrous ARS ACS grade?
When stored in a cool, dry place in a tightly sealed container, sodium sulfite anhydrous ARS ACS grade typically has a shelf life of 2-3 years.
2. Is this product compatible with acidic solutions?
Sodium sulfite reacts with acids to release sulfur dioxide gas, so it should be used cautiously in acidic environments.
3. What are the storage recommendations for this chemical?
Store in an airtight container away from moisture, heat, and incompatible substances like strong acids or oxidizing agents.
4. Can this grade be used for food applications?
While sodium sulfite is used in food preservation, the ARS/ACS grade is specifically intended for laboratory use and not certified for food applications.
5. What is the difference between anhydrous and hydrated sodium sulfite?
Anhydrous sodium sulfite contains no water molecules, while the hydrated form includes water in its crystal structure, affecting solubility and reactivity.
