Product Overview
This 0.1N Ammonium Iron(II) Sulphate solution offers laboratory professionals a ready-to-use reagent for precise redox titrations, eliminating the need for time-consuming preparation and standardization. The solution maintains exact 0.1 mol/L concentration of Fe²⁺ ions, stabilized with sulphuric acid to prevent oxidation, ensuring consistent performance in analytical procedures. Packaged in 500ml HDPE bottles with tamper-evident seals, the solution remains stable for extended periods when stored properly. The ammonium salt formulation provides better solubility compared to simple ferrous sulphate solutions, while the standardized normality guarantees accurate titration endpoints. Particularly effective in dichromate titrations and iron content determinations, this solution combines convenience with analytical reliability. The light green color serves as a visual indicator of the Fe²⁺ oxidation state, while the included Certificate of Analysis documents the exact molarity and expiration date for quality assurance.
FAQs
1. How should this solution be standardized before use?
While pre-standardized, periodic verification against potassium dichromate primary standard is recommended for critical applications.
2. What is the typical shelf life of this solution?
When stored unopened in original packaging, the solution maintains its titer for 6 months from date of manufacture.
3. Can this be used for colorimetric iron determinations?
The solution is primarily designed for titrimetric applications. For colorimetry, additional complexing agents would be required.
4. What precautions are needed during handling?
Wear chemical-resistant gloves as the solution contains sulphuric acid. Avoid contact with oxidizing agents that may alter the Fe²⁺ concentration.
5. Is this solution compatible with automatic titrators?
Yes, the solution’s stability and precise molarity make it suitable for both manual and automated titration systems.
