EDTA Disodium Salt 99% AR 500g RL – Analytical Reagent

EDTA Disodium Salt 99% AR 500g RL is a widely used laboratory chemical for analytical chemistry, complexometric titration, metal-ion determination, research and educational applications. EDTA stands for Ethylenediaminetetraacetic Acid, a polycarboxylic acid that acts as an effective chelating agent.

The disodium salt form is particularly useful for preparing aqueous EDTA solutions. In analytical chemistry, EDTA is commonly used because it can bind with various metal ions to form stable coordination complexes.

The 500g pack provides a practical quantity for laboratories performing regular analytical and research procedures. As an AR (Analytical Reagent) product, it is intended for applications where reagent quality and specified analytical characteristics are important.

Users should always verify the exact product grade, hydration state, assay, molecular weight and technical specifications from the current RL product documentation before use.

What is EDTA Disodium Salt?

EDTA is a synthetic chelating agent capable of binding metal ions through multiple donor atoms. Its full chemical name is ethylenediaminetetraacetic acid.

The disodium salt is commonly used because it is more convenient for preparing aqueous solutions than the free acid form.

Depending on the exact product, EDTA disodium salt may be supplied as an anhydrous compound or as a hydrated form. This distinction is important because the molecular weight and solution-preparation calculations differ between forms.

Therefore, laboratory users should always check the product label and CoA for the exact chemical form.

Why Choose EDTA Disodium Salt 99% AR 500g RL?

The 99% AR specification makes this product suitable for laboratories that require a relatively high-purity EDTA reagent for analytical work.

The product can be relevant to:

• University chemistry laboratories
• Pharmaceutical laboratories
• Research institutions
• Analytical laboratories
• Quality-control laboratories
• Water-testing laboratories
• Environmental laboratories
• Educational institutions
• Industrial laboratories

A 500g pack can also be useful for laboratories with regular EDTA consumption.

Complexometric Titration

One of the most important applications of EDTA is complexometric titration.

EDTA can form stable complexes with many metal ions. This property allows analytical chemists to determine the concentration of selected metal ions in a sample.

EDTA titration methods are commonly associated with the determination of ions such as:

• Calcium
• Magnesium
• Zinc
• Copper
• Nickel
• Lead
• Other suitable metal ions

The actual titration conditions depend on the metal ion, pH, indicator and analytical method being used.

Water Hardness Testing

EDTA is particularly important in water hardness analysis.

Water hardness is largely associated with dissolved calcium and magnesium ions. In suitable analytical methods, EDTA can react with these ions and allow their concentration to be determined through complexometric titration.

This makes EDTA disodium salt useful in:

• Water-quality laboratories
• Environmental laboratories
• Drinking-water testing
• Industrial water analysis
• Educational chemistry practicals

For accurate testing, laboratories should follow a validated or recognized analytical method.

EDTA as a Chelating Agent

EDTA is known as a chelating agent because it can surround and bind metal ions through multiple coordination sites.

The resulting complexes are often significantly more stable than simple metal-ion interactions. This property is central to many analytical chemistry applications.

Chelation is also relevant to chemical research, formulation science and laboratory sample preparation.

Analytical Reagent Grade

The AR (Analytical Reagent) designation indicates that the chemical is intended for analytical laboratory use according to the manufacturer’s specifications.

For analytical applications, users should consider:

• Assay/purity
• Impurity profile
• Hydration state
• Batch information
• Certificate of Analysis
• Method requirements

A reagent should not be assumed to be suitable for a highly specialized application simply because it is labeled AR; the actual product specification should be checked.

Preparation of EDTA Solutions

EDTA disodium salt can be used to prepare solutions of a desired concentration for laboratory analysis.

However, accurate preparation requires knowledge of the exact chemical form and molecular weight. For example, anhydrous EDTA disodium salt and hydrated EDTA disodium salt do not have the same molecular weight.

Therefore, before preparing a standard solution, laboratory personnel should verify the manufacturer’s stated molecular weight and assay.

For standardized titration procedures, the prepared EDTA solution may also require standardization according to the applicable analytical method.

Educational Laboratory Applications

EDTA disodium salt is a useful reagent for chemistry education because it demonstrates:

• Complex formation
• Coordination chemistry
• Chelation
• Metal-ion analysis
• Complexometric titration
• Analytical calculations

University and college chemistry laboratories can use appropriate EDTA procedures to teach students how analytical titration differs from conventional acid-base titration.

Research Applications EDTA Disodium Salt 99% AR 500g RL

Researchers may use EDTA disodium salt in experiments involving metal ions, coordination chemistry, sample preparation and analytical procedures.

It can also be encountered in biochemical and laboratory research where controlled metal-ion binding is relevant.

The suitability of the reagent depends on the research protocol and required purity. Sensitive research should be performed using a grade specifically validated for the intended purpose.
