Product Overview
This 0.1N zinc sulfate volumetric solution is a pre-standardized, high-purity reagent designed for precise titration applications in laboratory settings. Formulated under strict quality controls, it adheres to AVS TITRINORM® standards, ensuring accuracy and reproducibility in volumetric analysis. The solution is prepared using ultra-pure zinc sulfate heptahydrate dissolved in deionized water, with the concentration meticulously verified to 0.1 mol/L (0.1N) for direct use without further dilution. Its stability is enhanced with proprietary stabilizers to prevent precipitation or concentration drift over time. The solution is packaged in a high-density polyethylene (HDPE) bottle with a tamper-evident seal to maintain integrity during storage and handling. Ideal for complexometric titrations, particularly in EDTA-based methods, this solution eliminates the need for in-house standardization, saving time and reducing potential errors. The AVS TITRINORM® certification guarantees traceability to international reference materials, making it suitable for quality control, research, and educational laboratories requiring NIST-traceable standards.
FAQs
1. What is the exact molarity of this zinc sulfate solution?
The solution is precisely standardized to 0.1000 ± 0.0005 mol/L, with certification provided on the label.
2. Can this solution be used for complexometric titrations with EDTA?
Yes, it is specifically formulated for EDTA titrations where zinc ions serve as the titrant or back-titrant.
3. How should this solution be stored to maintain its certified concentration?
Store upright at 15-25°C in the original tightly closed bottle, away from direct sunlight and moisture.
4. Is this solution compatible with automatic titrators?
It is fully compatible with most automatic titrators, though we recommend verifying electrode compatibility with zinc solutions.
5. What documentation is provided with this volumetric solution?
Each bottle includes a certificate of analysis with traceability, expiry date, and standardized value at 20°C.
