Product Overview
EDTA tripotassium salt dihydrate AR is a high-purity chelating agent widely used in analytical laboratories for its exceptional ability to bind metal ions. This crystalline powder, classified as an Analytical Reagent (AR) grade, ensures minimal impurities, making it suitable for precise applications such as complexometric titrations and metal ion sequestration. Its dihydrate form enhances solubility in aqueous solutions, facilitating efficient chelation without residue formation. The tripotassium salt variant offers improved stability compared to other EDTA forms, ensuring consistent performance across diverse experimental conditions. Whether used in volumetric analysis or as a stabilizing agent in biochemical assays, this compound maintains its integrity under varying pH levels, providing reliable results. Its non-toxic nature and compatibility with most lab protocols further solidify its role as an indispensable reagent in research and quality control environments. The 500 g pack size offers an optimal balance between bulk availability and storage convenience, reducing the need for frequent reordering while maintaining freshness.
FAQs
1. What is the solubility of EDTA tripotassium salt dihydrate in water?
EDTA tripotassium salt dihydrate is highly soluble in water, typically dissolving at concentrations exceeding 100 g/L at room temperature, forming a clear, colorless solution.
2. Can this compound be used for hard water analysis?
Yes, it is commonly employed in hard water analysis due to its strong chelating properties, which allow it to bind calcium and magnesium ions effectively for accurate titration results.
3. What is the difference between EDTA tripotassium salt and disodium salt?
The tripotassium salt offers higher solubility in alkaline conditions and is often preferred for applications requiring stable pH environments, while the disodium salt is more common in neutral pH titrations.
4. How should this product be stored to maintain its shelf life?
Store in a tightly sealed container in a cool, dry place, away from direct sunlight and moisture, to preserve its chelating efficiency and prevent hydration changes.
5. Is this AR-grade EDTA suitable for food or pharmaceutical testing?
While it meets analytical standards, ensure compliance with specific regulatory requirements for food or pharmaceutical applications, as additional purity certifications may be necessary.
