Product Overview
EDTA disodium salt dihydrate (Ethylenediaminetetraacetic acid disodium salt dihydrate) is a highly versatile chelating agent widely used in laboratory settings for its ability to bind metal ions with exceptional stability. This ACS-grade variant ensures high purity and consistency, making it suitable for critical applications such as complexometric titrations, where precise metal ion quantification is essential. The dihydrate form enhances solubility in aqueous solutions, allowing for efficient use in buffer preparations, enzymatic reactions, and molecular biology protocols. Its strong chelating properties make it indispensable in preventing metal-catalyzed oxidation, ensuring the integrity of sensitive biochemical assays. The crystalline powder form provides ease of handling and accurate weighing, while the ACS certification guarantees adherence to stringent quality standards. Whether used in analytical chemistry, biochemistry, or environmental testing, this EDTA variant delivers reliable performance, minimizing interference from trace metal contaminants. Store in a cool, dry place to maintain stability and extend shelf life.
FAQs
1. What is the solubility of EDTA disodium salt dihydrate in water?
EDTA disodium salt dihydrate is highly soluble in water, with a solubility of approximately 100 g/L at 20°C, forming a clear, colorless solution.
2. Can this EDTA variant be used for calcium and magnesium titration in hard water analysis?
Yes, this ACS-grade EDTA disodium salt dihydrate is commonly employed for calcium and magnesium titration in hard water analysis due to its strong and selective metal-binding properties.
3. Is this product compatible with common laboratory buffers like Tris or phosphate buffers?
EDTA disodium salt dihydrate is generally compatible with Tris and phosphate buffers, but it is recommended to verify pH stability and potential precipitation in specific buffer compositions.
4. What is the difference between EDTA disodium salt dihydrate and its anhydrous form?
The dihydrate form contains two molecules of water per EDTA unit, which enhances solubility and ease of dissolution compared to the anhydrous form, which may require additional handling steps.
5. How should this product be stored to maintain its stability?
Store in a tightly sealed container in a cool, dry place, away from direct sunlight and moisture, to preserve its chelating efficiency and prevent degradation.
