Assertion: Toxic metal ions are removed by the chelating ligands.

Reason: Chelate complexes tend to be more stable.

1. Both assertion and reason are true and the reason is the correct explanation of assertion.

2. Both assertion and reason are true and the reason is not the correct explanation of assertion.

3. Assertion is true but the reason is false.

4. Assertion is false but the reason is true.


 


Hint: Metal poisoning is treated using chelation therapy

Toxic metal ions are removed by chelating ligands. When a solution of the chelating ligand is added to a solution containing

toxic metals ligands chelate the metal ions by the formation of a stable complex.

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