Disodium Edetate Dihydrate, EDTA-2Na

Properties
EDTA-2Na is a white crystalline powder that is soluble in water and has a weak acidic characteristic with a pH of about 5.3 .
It is a strong chelating agent capable of forming stable complexes with metal ions, which makes it useful in various applications where metal ion binding is necessary.
It is stable under normal conditions but should be stored away from heat and strong oxidizing agents .

Uses
In the industrial sector, it is used in chemical plating processes such as copper, gold, and lead-tin alloy plating, as well as in the electrochemical polishing of steel parts and pre-treatment for silver plating on copper items .
In detergents and cleaning agents, EDTA-2Na helps to soften water by chelating calcium and magnesium ions, enhancing the cleaning efficiency .
In cosmetics and personal care products, it acts as a stabilizer and chelating agent to prevent metal ion interference and extend the shelf life of products.
In agriculture, it is used in fertilizers to improve the uptake of nutrients by plants.
In food processing, according to the Chinese standard GB 2760—2014, EDTA-2Na can be used in a variety of food products within specified limits, such as fruit preserves, pickled vegetables, and various canned foods .
In chemical analysis, it is used for complexometric titration to determine the concentration of metal ions .
