Product Overview

This 0.1N (N/10) Hydrochloric Acid solution is a standardized volumetric reagent meticulously prepared for high-precision laboratory applications. Formulated with Analytical Reagent (AR) grade purity, it ensures minimal impurities and consistent normality, making it ideal for critical titration procedures where accuracy is paramount. The solution undergoes rigorous quality control to maintain its concentration stability over time, eliminating the need for frequent re-standardization in routine lab workflows. Its clear, colorless appearance indicates high purity, while the pre-diluted 0.1N concentration offers convenience for direct use in acid-base titrations, back-titrations, and volumetric analysis without additional preparation. The solution is packaged in high-density polyethylene (HDPE) bottles that resist chemical corrosion and prevent contamination, with tamper-evident seals to guarantee integrity upon delivery. Each batch is accompanied by a certificate of analysis (CoA) verifying its normality, ensuring traceability and compliance with laboratory standards. The balanced acidity profile makes it compatible with a wide range of indicators like phenolphthalein and methyl orange, while its low metal ion content prevents interference in sensitive analytical techniques. Whether used as a primary standard or for sample preparation, this HCl solution delivers reproducible results across multiple experimental setups.

FAQs

1. How do I verify the normality of this 0.1N HCl solution before use?

You can standardize the solution against a primary standard like sodium carbonate (Na₂CO₃) or borax using a known indicator. The procedure involves titrating a weighed amount of the primary standard with the HCl solution until the endpoint is reached, then calculating the exact normality based on the consumption volume.

2. Is this solution compatible with glass burettes and pipettes?

Yes, the solution is safe for use with standard borosilicate glassware. However, prolonged storage in glass containers may lead to minor leaching of silicates, so it’s recommended to transfer only the required volume for immediate use and store the bulk solution in its original HDPE bottle.

3. What is the shelf life of this 0.1N HCl solution, and how should it be stored?

The solution remains stable for up to 12 months from the date of manufacture when stored in a tightly sealed original container at room temperature (15–25°C). Avoid exposure to direct sunlight or heat sources, and ensure the cap is securely closed after each use to prevent concentration changes due to evaporation.

4. Can this solution be diluted further for lower concentrations?

While technically possible, diluting this pre-standardized 0.1N solution may introduce errors due to volume measurement inaccuracies. For concentrations below 0.1N, it’s advisable to prepare fresh dilutions from concentrated AR-grade HCl (36–38%) using deionized water and re-standardize the resulting solution.

5. Does this solution contain any stabilizers or preservatives?

No, this is a pure aqueous solution of HCl without added stabilizers or preservatives. The AR grade certification ensures that the only significant components are hydrochloric acid and deionized water, making it suitable for applications where chemical purity is critical.
