Ethylenediaminetetraacetic Acid Disodium Salt Dihydrate used in many
industry applications

Ethylenediaminetetraacetic Acid Disodium Salt Dihydrate (Na₂EDTA·2H₂O) is a widely used chelating agent with numerous industrial applications due to its ability to bind metal ions. Here's a list of some of its industrial uses:

1. Water Treatment: Na₂EDTA·2H₂O is used in water treatment to remove heavy metals and soften water by sequestering metal ions.
2. Food Industry: It acts as a preservative and stabilizer in food products, preventing oxidation and maintaining color and flavor by binding trace metals that catalyze degradation.
3. Agriculture: Used in agriculture as a micronutrient fertilizer, it supplies essential metal ions to plants and enhances their growth.
4. Pharmaceuticals: Na₂EDTA·2H₂O is used in pharmaceuticals to treat metal poisoning by chelating metal ions and facilitating their excretion from the body.
5. Cosmetics: It is incorporated into cosmetics and personal care products to stabilize formulations and improve shelf life by binding metal ions that could cause degradation.
6. Industrial Cleaning: Employed in industrial cleaning products, it removes metal deposits and scale from equipment and surfaces by chelating metal ions.
7. Pulp and Paper Industry: Used in the pulp and paper industry to control metal ions that can affect the bleaching process and paper quality.
8. Textile Industry: Na₂EDTA·2H₂O is used in the textile industry to improve dyeing processes and color fastness by sequestering metal ions that can interfere with dyes.
9. Analytical Chemistry: It serves as a standard reagent in titrations and other analytical procedures to determine metal ion concentrations in solutions.
10. Plating and Metal Finishing: In metal plating and finishing processes, Na₂EDTA·2H₂O helps to control metal ion concentrations and improve the quality of the final product.
11. Environmental Remediation: It is used in environmental remediation efforts to clean up heavy metal contamination in soils and water by binding and removing metal ions.
12. Detergents: Na₂EDTA·2H₂O is added to detergents to enhance their cleaning efficiency by binding hard water ions and preventing their interference with the detergent's action.
