Product Overview
This 0.25M (0.5N) bromine-bromate/bromide standardized solution is a precision-formulated reagent designed for high-accuracy redox titrations in laboratory settings. The solution combines bromine, bromate, and bromide ions in a stabilized aqueous matrix, ensuring consistent performance and minimal degradation over time. Pre-standardized to exact molarity, it eliminates the need for in-house standardization, saving time while maintaining analytical reliability. The reagent is prepared using ultra-pure water and analytical-grade salts to minimize impurities that could interfere with titration endpoints. Its stable oxidation potential makes it particularly suitable for bromine number determinations in petroleum products, olefin analysis, and other applications requiring controlled oxidative conditions. The solution is packaged in an amber glass bottle to prevent photodegradation, with a secure PTFE-lined cap to avoid contamination or evaporation. Each batch undergoes rigorous quality control, including potentiometric verification, to ensure compliance with international analytical standards. The 1L pack size provides sufficient volume for multiple experiments while maintaining freshness throughout its usable shelf life.
FAQs
1. What is the exact shelf life of this bromine-bromate/bromide solution when stored properly?
The solution remains stable for 12 months from the date of manufacture when stored in its original amber bottle at 15-25°C, away from direct sunlight and moisture. Always check the label for the specific expiration date.
2. Can this solution be used directly for Karl Fischer titrations?
No, this reagent is specifically formulated for redox titrations involving bromine/bromate chemistry. For Karl Fischer titrations, you would need a dedicated Karl Fischer reagent with iodine and sulfur dioxide components.
3. What material is recommended for the burette when using this solution?
Use a borosilicate glass burette with PTFE or glass stopcocks. Avoid rubber components as they may react with bromine. Rinse the burette with the solution before use to prevent dilution errors.
4. How does the presence of both bromate and bromide ions affect the titration?
The bromate (BrO₃⁻) acts as the primary oxidizing agent, while bromide (Br⁻) participates in the redox equilibrium, generating bromine (Br₂) in acidic conditions. This dual-ion system creates a buffered oxidative environment for precise endpoint detection.
5. Is this solution compatible with automatic titrators?
Yes, the solution is compatible with most automatic titrators equipped for redox titrations. Ensure the instrument’s electrode is suitable for bromine-based systems (e.g., platinum or gold electrodes) and calibrate with the same solution for accuracy.
