EDTA Solution 0.1 N is a standardized aqueous solution of ethylenediaminetetraacetic acid (EDTA) with a normality of 0.1 N, intended for complexometric titrations, metal ion determination, and laboratory applications requiring precise chelating strength.
🏭⚗️ Production
EDTA 0.1 N solution is prepared by dissolving accurately weighed high-purity disodium EDTA or EDTA tetrasodium salt in distilled water. The solution is adjusted to the desired normality and standardized against a primary metal ion standard, then packaged in airtight, moisture-resistant containers to maintain chemical stability and prevent contamination.
🔬 Properties
EDTA (C₁₀H₁₆N₂O₈) is a white, crystalline solid that forms a clear, colorless solution in water. The 0.1 N solution is slightly alkaline with a pH around 8–9. It acts as a strong chelating agent, forming stable complexes with divalent and trivalent metal ions such as Ca²⁺, Mg²⁺, and Fe³⁺.
🧪 Applications
EDTA 0.1 N is widely used in analytical and pharmaceutical laboratories for complexometric titrations, determination of hardness in water, metal ion analysis, and standardization of solutions containing metal ions. It is also employed in pharmaceutical formulations and buffer solutions where metal ion chelation is required.
⚠️ Safety
EDTA solution is generally considered to have low toxicity but may cause irritation to the eyes and skin. Handle in a well-ventilated area using gloves, goggles, and protective clothing. Store in tightly-sealed containers in a cool, dry, well-ventilated place, and dispose of waste according to laboratory safety protocols.
