Definition: The process of converting a substance that has optical activity into a mixture that contains equal amounts of its two mirror-image forms.

Example: The racemization of the compound resulted in a mixture that was no longer optically active.

Definition: To change a substance that has two forms (enantiomers) into a mixture that contains equal amounts of both forms.

Example: The chemist needed to racemize the compound to study its properties more effectively.
