EDTA 2NA is white crystalline powder, soluble in water, almost insoluble in ethanol, ether, its aqueous solution pH is about 4-5.Disodium EDTA, also known as edta-2na, is a good complexing agent in chemistry. It has six coordination atoms, forming a complexcalled chelate. Pure EDTA 2NA is an important kind of complexing agent.

Disodium edetate, also known as EDTA-2Na, is a good complexing agent in chemistry. It has six coordinating atoms, and the complex formed is called a chelate. EDTA is often used in coordination titration. The content of metal ions is generally determined. EDTA has important applications in the dye, food, pharmaceutical and other industries.
Disodium edetate is a white crystalline granule or powder which is odorless and tasteless. It is soluble in water and extremely difficult to dissolve in ethanol. It is an important chelating agent that sequesters metal ions in solution. It prevents discoloration, deterioration, turbidity and oxidation loss of vitamin C caused by metal, and also improves the oxidation resistance of oils and fats (a trace amount of metals such as iron and copper in oils and fats promotes oxidation of oils and fats).

EDTA-2Na is important complexing agent. It is used as fixing bath for bleaching, dyeing auxiliary agent, fiber treatment agent, cosmetics additive, blood anticoagulation, detergent, stabilizing agent, synthetic rubber, polymerization initiator and quantitative analysis agent of heavy metal.
