محلول دی سدیم ادتا 0.05

EDTA Na₂ Solution 0.05 mol/L is a standardized aqueous solution of disodium ethylenediaminetetraacetate (Na₂EDTA), widely used in pharmaceutical, biochemical, and analytical laboratories. It functions as a strong chelating agent, forming stable complexes with divalent and trivalent metal ions, particularly calcium and magnesium, making it ideal for complexometric titrations and metal ion control in formulations.

🏭⚗️ Production
The solution is prepared by dissolving high-purity disodium EDTA in distilled or deionized water. pH is adjusted with sodium hydroxide to ensure full solubility and stability. After preparation, it is standardized against a primary standard such as calcium carbonate or zinc sulfate to verify accurate molarity (0.05 mol/L). The solution is stored in tightly sealed, chemically resistant bottles to prevent contamination and evaporation.

🔬 Properties
A clear, colorless, and odorless liquid, freely soluble in water. It exhibits excellent stability under normal laboratory conditions and maintains strong metal-binding capacity across a broad pH range. The solution is non-volatile, non-flammable, and shows minimal reactivity with most laboratory reagents.

🧪 Applications
In pharmaceutical and analytical laboratories, EDTA Na₂ Solution 0.05 mol/L is used in complexometric titrations for determination of metal ions such as calcium, magnesium, zinc, and copper. It also serves in pharmaceutical assay procedures, buffer preparations, stability testing, and as a chelating agent to inhibit metal-catalyzed degradation in formulations and analytical methods.

⚠️ Safety
The solution is of low toxicity but may cause mild irritation to skin or eyes upon contact. Standard laboratory protective equipment (gloves, goggles, lab coat) should be worn. Store in a cool, dry place, away from acids and oxidizing agents. Dispose of waste according to laboratory and environmental safety guidelines.
