Product Overview
This 0.5N potassium hydroxide volumetric solution is a high-precision analytical reagent formulated under strict AVS TITRINORM® standards, ensuring exceptional accuracy for titration applications. The solution is prepared using ultra-pure KOH dissolved in deionized water, with the concentration standardized to 0.5 mol/L (0.5N) for consistent performance in quantitative analyses. The AVS TITRINORM® certification guarantees traceability to primary standards, eliminating the need for in-house standardization while maintaining compliance with international pharmacopeia and ISO guidelines. Packaged in a 1L HDPE bottle with a tamper-evident seal, the solution remains stable for extended periods when stored properly, resisting carbonation and concentration drift. Its low carbonate content (<0.2%) minimizes errors in sensitive titrations, while the absence of heavy metal impurities (Pb <0.0001%, Fe <0.0002%) prevents interference in spectrophotometric applications. The solution's homogeneous composition ensures immediate readiness for use without requiring filtration or dilution, making it ideal for high-throughput laboratories where reproducibility is critical.
FAQs
1. What is the shelf life of this 0.5N KOH volumetric solution when unopened?
The unopened solution maintains its certified concentration for 24 months from the date of manufacture when stored at 15-25°C in its original packaging.
2. Can this solution be used for non-aqueous titrations?
While primarily designed for aqueous titrations, it can be employed in non-aqueous systems with proper solvent compatibility testing, though recalibration may be required.
3. How does the AVS TITRINORM® certification differ from standard analytical grade?
AVS TITRINORM® solutions undergo additional verification against primary standards with documented uncertainty values, providing higher metrological traceability than conventional analytical grades.
4. What precautions should be taken when handling this concentrated KOH solution?
Always wear nitrile gloves, safety goggles, and a lab coat. Work under a fume hood due to potential exothermic reactions and corrosive vapor release upon contact with acids.
5. Is this solution compatible with automatic titrators?
Yes, the solution’s low viscosity and absence of particulate matter make it fully compatible with most automatic titration systems without requiring pre-treatment.
