Product Overview
This AVS TITRINORM® sulfuric acid volumetric solution delivers laboratory-grade precision with a standardized 5 mol/L (10 N) concentration, packaged in a 2.5L safe-break bottle for enhanced handling safety. The solution undergoes rigorous quality control to maintain ±0.1% accuracy, meeting ISO 17025 and ISO 17034 standards for volumetric analysis. Its TITRINORM® certification ensures traceability to NIST reference materials, eliminating the need for in-house standardization. The safe-break bottle design features an integrated neck ring that prevents accidental spills during dispensing, while the HDPE material provides excellent chemical resistance. Each batch includes a certificate of analysis with lot-specific data, including density (1.29 g/cm³ at 20°C), exact molarity, and expiry date. The solution remains stable for 36 months when stored unopened at 15-25°C, with the amber bottle offering UV protection to prevent degradation. Its low heavy metal content (<0.1 ppm) and particle-free formulation make it ideal for sensitive analytical applications where consistency is critical.
FAQs
1. What is the exact molarity tolerance for this sulfuric acid solution?
The solution maintains a molarity tolerance of ±0.1% from the stated 5.000 mol/L concentration, as verified by potentiometric titration against primary standards.
2. Can this solution be used with automatic titrators?
Yes, the solution is compatible with most automatic titrators, though we recommend verifying the instrument’s chemical resistance to concentrated sulfuric acid first.
3. What alternatives exist for lower concentration requirements?
For applications requiring diluted solutions, we offer 1 mol/L and 0.1 mol/L sulfuric acid standards in the same TITRINORM® quality grade.
4. How should I dispose of expired sulfuric acid solution?
Neutralize with sodium bicarbonate solution to pH 6-8 before disposal according to your institution’s chemical waste protocols and local environmental regulations.
5. Does the safe-break bottle require special storage conditions?
Store upright in a dedicated acid cabinet at 15-25°C, away from organic materials and oxidizing agents, despite the bottle’s safety features.
