Paragraph: EDTA is used as a complexing agent in chemical analysis. Solution of EDTA usually containing the disodium salt Na ₂ H ₂ EDTA are also used to treat heavy metal poisoning. EDTA is a hexadentate ligand having the following structure. Question: EDTA forms stable complexes with many metal ions due to

Options

  1. AHigh negative charge density
  2. BChelation
  3. CLow negative charge density
  4. DBecause it is very weak field ligand

Correct answer

B. Chelation

Step-by-step solution

Chelation increases stability of complexes
