EDTA Di Sodium Salt- 100gm Packs

EDTA Disodium Salt is a water-soluble chelating agent widely used in analytical chemistry, chemical research, and laboratory solution preparation. Chemically known as disodium ethylenediaminetetraacetate, it binds metal ions such as calcium, magnesium, and iron through coordination with its nitrogen and oxygen donor atoms. This metal-binding property makes EDTA Disodium Salt valuable in complexometric titrations, water hardness determination, metal-ion analysis, and experiments investigating coordination chemistry. It is also used in selected buffer systems, sample preparation procedures, and research protocols where controlling the availability of metal ions is important. EDTA Disodium Salt is commonly supplied as a white crystalline powder and is soluble in water. The exact molecular formula and molecular weight depend on whether the material is anhydrous or the dihydrate. Laboratories should confirm the chemical form and product specifications before preparing solutions or conducting quantitative experiments.

Frequently Asked Questions About EDTA Disodium Salt

What is EDTA Disodium Salt used for in laboratories?

EDTA Disodium Salt is primarily used as a chelating agent in analytical chemistry. Common applications include complexometric titrations, determination of water hardness, metal-ion analysis, coordination chemistry experiments, and selected research procedures where binding calcium, magnesium, or other metal ions is necessary.

What is the chemical formula of EDTA Disodium Salt?

The anhydrous form has the molecular formula C₁₀H₁₄N₂Na₂O₈, while the commonly used dihydrate has the formula C₁₀H₁₄N₂Na₂O₈·2H₂O. The dihydrate has a molecular weight of approximately 372.24 g/mol, compared with 336.21 g/mol for the anhydrous form.

What is the CAS number of EDTA Disodium Salt?

The CAS number 139-33-3 identifies anhydrous EDTA Disodium Salt, while 6381-92-6 identifies its dihydrate. Because these forms differ in water content and molecular weight, laboratories should confirm which form is supplied before using the substance in calculations, solution preparation, or procurement records.

Why is EDTA Disodium Salt used in water hardness determination?

EDTA forms stable complexes with calcium and magnesium ions, which contribute to water hardness. In a standard complexometric titration, a measured sample is titrated with an EDTA solution using a suitable pH buffer and indicator. The endpoint helps determine the hardness, provided the procedure and reagent concentrations are appropriate.

How should EDTA Disodium Salt be stored and handled safely?

Keep the material in a tightly closed, clearly labelled container in a cool, dry, well-ventilated area. Minimise dust formation and avoid contact with eyes and unnecessary skin exposure. Wear suitable laboratory gloves and safety goggles, consult the current Safety Data Sheet, and follow institutional procedures for spills and chemical waste disposal.

Storage Conditions for EDTA Disodium Salt

Store EDTA Disodium Salt in a tightly closed, compatible container in a cool, dry, well-ventilated location, protected from excessive moisture and contamination. Keep the material properly labelled and segregated from incompatible substances according to the applicable safety guidance. Avoid unnecessary dust formation during handling, and follow the product-specific Safety Data Sheet for any additional storage requirements.

Precautions for Handling EDTA Disodium Salt

Review the current Safety Data Sheet before use and wear suitable laboratory gloves, safety goggles, and protective clothing. Avoid generating or inhaling dust and prevent unnecessary contact with skin and eyes. Use appropriate laboratory ventilation when weighing or transferring powdered material. Prepare solutions using the specified chemical form and appropriate calculations, and manage spills and waste according to institutional procedures and applicable regulations.
