Product Overview
This 0.05M (0.05N) cerium(IV) sulphate standardized solution is a high-precision analytical reagent traceable to NIST standards, ensuring reliable and reproducible results in redox titrations. The solution is prepared using ultra-pure cerium sulphate in a sulfuric acid matrix, providing exceptional stability and resistance to reduction over extended storage periods. Its standardized concentration eliminates the need for in-house standardization, saving valuable lab time while maintaining accuracy. The analytical grade purity guarantees minimal interference from impurities, making it ideal for demanding volumetric applications. Packaged in a high-density polyethylene bottle with a tamper-evident seal, the solution maintains its integrity during transport and storage. The amber-colored bottle provides additional protection against light-induced degradation, preserving the cerium(IV) oxidation state. Each batch undergoes rigorous quality control testing to verify concentration and purity, with certificates of analysis available upon request.
FAQs
1. What is the exact molarity of this cerium(IV) sulphate solution?
The solution is standardized to 0.0500M (±0.0005M) concentration, traceable to NIST reference materials for assured accuracy in titrimetric applications.
2. Can this solution be used for back titrations involving ferrous ions?
Yes, this cerium(IV) sulphate solution is particularly effective for ferrous ion titrations due to its stable oxidation state and sharp endpoint detection with appropriate indicators.
3. What is the recommended storage temperature for maintaining stability?
Store the solution at room temperature (15-25°C) in its original tightly sealed container, protected from direct sunlight to prevent potential reduction of cerium(IV).
4. How does the NIST traceability benefit my analytical work?
NIST traceability ensures the concentration is verified against primary standards, providing documented accuracy that supports GLP/GMP compliance and eliminates the need for frequent in-house standardization.
5. What safety precautions should be taken when handling this solution?
Always wear appropriate PPE including nitrile gloves and safety goggles, as the solution contains sulfuric acid. Work in a well-ventilated area or fume hood when handling large volumes.
