Question

Philoid · Accepted Answer

Assertion and the reason both are true, and the reason is the correct explanation of assertion.

When a solution of chelating ligand (like D-penicillamine) is added to solution containing toxic metals ligands (like excess iron and copper) the chelating ligand immediately transforms the metal ions by formation of stable complex, that is how toxic metal ions are removed by chelating ligands.

Eg- EDTA is an important chelating ligand.
