Product Name – Oxalic acid, 0.5 mol/L (1 N) AVS TITRINORM® volumetric solution
Quantity/Pack Size – 1 L
Form – Liquid (volumetric solution)
Grade – AVS TITRINORM® (analytical standard)
Application – Primary standard for acid-base titrations, redox titrations
Product Overview
This 0.5 mol/L (1N) oxalic acid volumetric solution represents the gold standard for analytical titrations, formulated under stringent AVS TITRINORM® protocols to ensure unmatched accuracy and reproducibility. As a primary standard solution, it eliminates the need for tedious standardization procedures while maintaining traceability to international reference materials. The solution is prepared using ultra-pure oxalic acid dihydrate dissolved in deionized water, with precise molarity verification through gravimetric analysis. Its exceptional stability is achieved through specialized packaging that prevents CO₂ absorption and concentration drift over time. The solution’s low heavy metal content (<0.5 ppm) and negligible chloride interference make it ideal for demanding applications where trace impurities could compromise results. Each batch undergoes rigorous quality control, including potentiometric titration verification and refractive index measurement, with certificates of analysis provided for full documentation. The amber glass bottle with tamper-evident seal ensures both light protection and sample integrity during storage and transport.
FAQs
1. What is the exact molarity of this oxalic acid solution?
The solution is precisely standardized to 0.5000 ± 0.0005 mol/L (1.0000 ± 0.0010 N) at 20°C, with batch-specific certification provided.
2. Can this solution be used for permanganate titrations?
Yes, this oxalic acid solution serves as an excellent primary standard for potassium permanganate standardization in redox titrations due to its stable oxidation state and precise concentration.
3. What is the shelf life when stored properly?
When stored unopened in its original packaging at 15-25°C, the solution maintains its certified concentration for 24 months from the date of manufacture.
4. Does this solution require any preparation before use?
No preparation is needed – the solution is ready-to-use directly from the bottle, with no dilution or standardization required for most applications.
5. What material is the bottle cap made from?
The bottle features a polypropylene screw cap with a PTFE-faced liner to prevent contamination and ensure chemical resistance during storage.
