Grade – AVS TITRINORM® (Analytical Volumetric Standard)
Application – Titrimetry, acid-base titrations, volumetric analysis
Product Overview
This 0.357 mol/L hydrochloric acid volumetric solution is a pre-standardized AVS TITRINORM® grade reagent designed for high-precision analytical applications. The solution undergoes rigorous quality control to ensure concentration accuracy within ±0.2% of the labeled value, eliminating the need for in-house standardization. Formulated with ultra-pure hydrochloric acid and deionized water, it maintains exceptional stability with minimal evaporation or concentration drift when stored properly. The AVS TITRINORM® certification guarantees traceability to primary standards, making it ideal for laboratories requiring NIST-comparable accuracy. Packaged in a high-density polyethylene bottle with a tamper-evident seal, the solution remains contaminant-free during storage and handling. The amber tint of the bottle provides additional protection against photodegradation, preserving the solution’s integrity over its 24-month shelf life. Each batch is accompanied by a certificate of analysis detailing the exact molar concentration, density, and purity parameters, ensuring full compliance with ISO 17025 standards for volumetric solutions.
FAQs
1. What is the exact concentration tolerance for this volumetric solution?
The solution maintains a concentration accuracy of ±0.2% relative to the labeled 0.357 mol/L value, as guaranteed by the AVS TITRINORM® certification process.
2. Can this solution be used directly without further standardization?
Yes, the AVS TITRINORM® designation indicates this solution is pre-standardized and ready for immediate use in titrations without requiring additional standardization procedures.
3. What material is used for the bottle and cap?
The solution is packaged in a high-density polyethylene bottle with a polypropylene screw cap, both materials being chemically resistant to hydrochloric acid.
4. How should I verify the solution’s concentration if required?
While pre-standardized, you can verify concentration by titrating against a primary standard like sodium carbonate using methyl orange as an indicator, though this is typically unnecessary for routine applications.
5. What’s the difference between this and regular laboratory-grade HCl?
Unlike standard laboratory-grade HCl, this volumetric solution undergoes precise dilution to an exact molar concentration and includes certification documentation, making it suitable for quantitative analytical work where concentration accuracy is critical.
