Answer: One way to separate a racemic mixture is through Crystallization.
Explanation:
A separation of a racemic mixture into their component enantiomers, is well know as "resolution"
When separating a racemic mixture of tartaric acid, the easiest way to do it, is by crystiallization.
As we can see in the diagram, we introduce a pure enantiomer seed that will start the desire conglomerate, and under repetead cycles of cooling and heating, the pure conglomerate crystal will grow, thereby leaving the other enantiomer in solution.
