Product Overview
EDTA Disodium Salt 0.05N Standardized Solution is a pre-prepared, high-precision reagent designed for accurate chelation titrations in laboratory settings. This solution is standardized to 0.025M (0.05N) concentration, ensuring consistent and reliable results in complexometric titrations without requiring additional dilution or preparation. The disodium salt form of EDTA (Ethylenediaminetetraacetic acid) provides enhanced solubility in aqueous solutions, making it ideal for determining metal ion concentrations, particularly calcium and magnesium in water hardness testing. The solution is stabilized to prevent degradation, offering an extended shelf life when stored under recommended conditions. Its analytical reagent (AR) grade guarantees minimal impurities, reducing interference in sensitive applications. The ready-to-use format eliminates the need for manual weighing or dissolution, saving time while maintaining accuracy. This solution is particularly valuable in environments where reproducibility and precision are critical, such as quality control laboratories, environmental testing facilities, and educational institutions conducting quantitative analysis.
FAQs
1. What is the exact molarity and normality of this EDTA solution?
The solution is standardized to 0.025M molarity, which corresponds to 0.05N normality for chelation titrations.
2. Can this solution be used directly for water hardness testing?
Yes, this pre-standardized 0.05N EDTA solution is ready for direct use in water hardness titrations without requiring further dilution.
3. What is the typical shelf life of this standardized solution?
When stored in a tightly sealed container at room temperature, the solution maintains its standardization for 12 months from the date of manufacture.
4. Is this EDTA solution compatible with automatic titrators?
The solution is fully compatible with both manual and automatic titration systems, provided the equipment is calibrated for 0.05N solutions.
5. What precautions should be taken during storage to maintain accuracy?
Store the solution in its original container away from direct sunlight and temperature fluctuations. Avoid contamination by using clean pipettes for dispensing.
