Assertion: Toxic metal ions are removed by the chelating ligands.
Reason: Chelate complexes tend to be more stable.
Options
Assertion and reason both are true, reason is correct explanation of assertion.
Assertion and reason both are true but reason is not the correct explanation of assertion.
Assertion is true, reason is false.
Assertion is false, reason is true.
Solution
Assertion and reason both are true, reason is correct explanation of assertion.
Explanation:
When a solution of chelating ligand is added to solution containing toxic metals ligands chelates the metal ions by formation of stable complex.
