Product Overview
This 0.02 mol/L (0.02N) hydrochloric acid volumetric solution is a pre-standardized, ready-to-use reagent designed for high-precision analytical applications. Formulated under the AVS TITRINORM® brand, it adheres to strict quality control measures, ensuring batch-to-batch consistency and traceable certification for reliable titration results. The solution is prepared using ultra-pure hydrochloric acid dissolved in deionized water, with the concentration meticulously verified against primary standards to eliminate the need for in-house standardization. Its low normality (0.02N) makes it particularly suitable for titrations requiring high sensitivity, such as weak base determinations or micro-scale analyses. The solution is stabilized to minimize concentration drift over time and is supplied in a high-density polyethylene (HDPE) bottle with a tamper-evident seal to prevent contamination or evaporation. The AVS TITRINORM® grade guarantees compliance with international pharmacopeia standards (USP/EP/JP), making it a trusted choice for laboratories where accuracy and reproducibility are critical. The solution’s clarity and absence of interfering impurities further enhance its suitability for spectrophotometric or electrochemical detection methods post-titration.
FAQs
1. What is the shelf life of this 0.02N hydrochloric acid volumetric solution?
The solution remains stable for 12 months from the date of manufacture when stored unopened at 15–25°C. Once opened, use within 3 months for optimal accuracy, as exposure to air may gradually alter the concentration due to evaporation or CO₂ absorption.
2. Can this solution be used directly for Karl Fischer titration?
No, this hydrochloric acid solution is not suitable for Karl Fischer titration, which requires a non-aqueous, anhydrous reagent system. This product is specifically standardized for acid-base titrations in aqueous media.
3. Is the concentration certificate provided with each bottle?
Yes, every bottle includes a batch-specific certificate of analysis (CoA) detailing the exact molarity, uncertainty value, traceability to NIST standards, and expiration date. The CoA is affixed to the label or inserted inside the packaging.
4. What material is the bottle cap made of, and is it resistant to HCl vapors?
The bottle cap is made of high-density polyethylene (HDPE) with a polypropylene (PP) liner, both of which are chemically resistant to hydrochloric acid vapors. The design includes a dual-seal mechanism to prevent leakage or vapor escape during storage.
5. How does the AVS TITRINORM® grade differ from standard analytical-grade HCl?
AVS TITRINORM® solutions undergo additional validation steps, including gravimetric verification against primary standards and stricter impurity profiling (e.g., <0.0001% heavy metals). This ensures higher traceability and lower measurement uncertainty compared to generic analytical-grade HCl, which may require in-house standardization.
