Question

why edta is acts as best complexing?​

Answer 1

Answer:

Complexing Metals The unusual property of EDTA is its ability to chelate or complex metal ions in 1:1 metal-to-EDTA complexes. The fully deprotonated form (all acidic hydrogens removed) of EDTA binds to the metal ion

Answer 2

Answer:

Why is EDTA an effective complexing agent?

Food spoilage is often promoted by naturally-occurring enzymes that contain transition-metal ions. These enzymes catalyze the chemical reactions that occur during spoilage. EDTA deactivates these enzymes by removing the metal ions from them and forming stable chelates with them.

Is EDTA a complexing agent?

EDTA was patented in Germany in 1935 by F. Munz. The molecule is a substituted diamine (Figure 1) usually marketed as its sodium salts. It is a powerful complexing agent of metals and a highly stable molecule, offering a considerable versatility in industrial and household uses2 (Table 1).
