Product Overview
Sodium nitrite ARS, ACS grade is a high-purity chemical compound designed for demanding laboratory applications where precision and consistency are critical. This crystalline powder meets stringent American Chemical Society (ACS) and Analytical Reagent Standard (ARS) specifications, ensuring minimal impurities and reliable performance in quantitative analyses. Its stable chemical properties make it indispensable for titrations, where accurate endpoint detection is essential, as well as in corrosion testing protocols where controlled nitrite concentrations are required. The compound’s solubility in water (45 g/100 mL at 20°C) allows for easy preparation of standard solutions, while its oxidizing nature enables diverse reactions in synthetic chemistry. Packaged in airtight containers to prevent moisture absorption and oxidation, this sodium nitrite maintains its integrity during storage and handling. Researchers benefit from its consistent assay values (typically ≥99.0%), which eliminate variability in experimental results. The ACS certification guarantees compliance with international quality benchmarks, making it suitable for calibration standards and reference materials in analytical laboratories. Its role as a corrosion inhibitor in metal treatment processes further extends its utility across industrial research applications.
FAQs
1. What is the difference between ARS and ACS grades in sodium nitrite?
ARS grade follows Indian analytical reagent standards, while ACS grade meets American Chemical Society specifications. Both ensure high purity but may differ slightly in impurity profiles and certification requirements.
2. Can this sodium nitrite be used for food preservation applications?
This product is lab-grade and not certified for food use. Food-grade sodium nitrite requires additional purity standards and regulatory approvals that differ from analytical reagent specifications.
3. What precautions should be taken when handling this chemical?
Always use in a well-ventilated fume hood, wear nitrile gloves and safety goggles, and avoid inhalation. Sodium nitrite is toxic if ingested and may form explosive mixtures with combustible materials.
4. How should unused sodium nitrite be disposed of?
Dissolve in plenty of water, neutralize if required, then dispose through authorized chemical waste channels. Never discard in regular trash or drainage systems due to environmental hazards.
5. What is the typical shelf life of this product when stored properly?
When kept in its original sealed container away from moisture and light, sodium nitrite maintains its specified purity for 24-36 months from the date of manufacture.
