EDTA Di Sodium Salt – 500 gram Packs

EDTA Disodium Salt is a chelating agent widely used in analytical chemistry, educational experiments, and scientific research. Also known as disodium ethylenediaminetetraacetate, it binds metal ions such as calcium, magnesium, and iron through the formation of coordination complexes. This property makes EDTA Disodium Salt useful for complexometric titrations, water hardness determination, metal-ion analysis, and investigations involving coordination chemistry. It is commonly encountered as a white crystalline powder and is used to prepare aqueous solutions for suitable laboratory procedures. The compound is particularly valuable in experiments requiring controlled metal-ion interactions and quantitative analysis. Its solubility and complex-forming behaviour depend on factors such as pH and the metal ion involved. EDTA Disodium Salt is available in anhydrous and hydrated forms, so the chemical identity should be confirmed before solution preparation or analytical calculations. Its suitability depends on the specified grade and the requirements of the intended laboratory method.

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, water hardness determination, metal-ion analysis, coordination chemistry experiments, and selected research procedures where binding calcium, magnesium, or other suitable metal ions is required.

What is the chemical formula of EDTA Disodium Salt?

The anhydrous form has the molecular formula C₁₀H₁₄N₂Na₂O₈, while the dihydrate has the formula C₁₀H₁₄N₂Na₂O₈·2H₂O. Their molecular weights are approximately 336.21 g/mol and 372.24 g/mol, respectively. Confirm the supplied form before preparing solutions or performing quantitative calculations.

What is the CAS number of EDTA Disodium Salt?

CAS number 139-33-3 identifies anhydrous EDTA Disodium Salt, while 6381-92-6 identifies the dihydrate. These identifiers correspond to different chemical forms, so the correct number should be selected according to the product’s actual composition and documentation.

How does EDTA Disodium Salt help determine water hardness?

EDTA forms complexes with calcium and magnesium ions, which contribute to water hardness. In a complexometric titration, a measured water sample is titrated with a suitable EDTA solution under controlled pH conditions using an appropriate indicator. The titration result is then used to calculate water hardness.

How should EDTA Disodium Salt be stored and handled?

Store EDTA Disodium Salt in a tightly closed, labelled container in a cool, dry location. Avoid unnecessary dust formation and contact with eyes or skin. Wear appropriate laboratory gloves and safety goggles, consult the current Safety Data Sheet, and follow institutional procedures for chemical handling, spills, and waste disposal.

Storage Conditions for EDTA Disodium Salt

Store EDTA Disodium Salt in its original, compatible, tightly closed container in a cool, dry, well-ventilated area. Protect the material from excessive moisture and contamination, and keep it properly labelled. Minimise dust formation during storage and transfer. Follow the product-specific Safety Data Sheet for any additional storage conditions or segregation 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 ventilation when weighing or transferring the powder. Prepare solutions using the correct hydrated or anhydrous form, and follow institutional procedures for spill management and chemical waste disposal.
