Description

Edta 2 sodium EDTA 2NA is a white crystalline powder, soluble in water, almost insoluble in ethanol, ether, the pH of its aqueous solution is about 4-5. Disodium EDTA, also known as edta-2na, is a good complexing agent in chemistry. It has six coordinating atoms that form a complex called a chelate. Pure EDTA 2NA is an important type of complexing agent.
What is Edta 2 sodium?

Ethylenediaminetetraacetic acid disodium salt (EDTA 2Na) EDTA 2Na (disodium ethylenediaminetetraacetic acid) is a chelating agent used to separate and reduce the reactivity of metal ions that may be present in many industrial and personal care products. be used

Does EDTA react with sodium?

While the complexes of EDTA with sodium and potassium ions are weak compared to those formed with many other metal ions, the complexation of EDTA by these two metal ions may be important under certain conditions.
Is EDTA acidic or basic?

The chelating agent commonly used for calcification is ethylenediaminetetraacetic acid (EDTA). Although EDTA is nominally acidic, it does not act like mineral or organic acids, but instead binds metal ions, especially calcium and magnesium.

What salts are in EDTA?

EDTA is available as several salts, notably disodium EDTA, sodium calcium edetate, and tetrasodium EDTA, but they all work similarly. Except where otherwise noted, data are presented for materials in their standard state (at 25 °C [77 °F], 100 kPa).
What is the use of EDTA 2NA?

EDTA is often used in coordination titrations. The content of metal ions is generally determined. EDTA has important applications in paint, food, pharmaceutical and other industries.
Disodium edetate is a white crystalline granule or powder that is odorless and tasteless. It is soluble in water and hardly soluble in ethanol.

It is an important chelating agent that separates metal ions in solution. It prevents discoloration, spoilage, turbidity and oxidation loss of vitamin C caused by metal, and also improves the oxidation resistance of oils and fats (small amounts of metals such as iron and copper in oils and fats cause oxidation of oils and fats).

EDTA-2Na is an important complexing agent. It is used as a stabilizing bath for bleaching, dyeing auxiliary agent, fiber treatment agent, cosmetic additive, blood anticoagulant, detergent, stabilizing agent, synthetic rubber, polymerization initiator, and quantitative decomposition agent of heavy metals.

In general, the addition of the chelating agent Na2EDTA improves charge acceptance, discharge capacity by 10-20%, and increases the cycle life of lead-acid batteries. The superior electrochemical performance is due to the dissociation of PbSO4 in the presence of the chelating agent Na2EDTA.
