Enantiomeric purity can be achieved by various techniques, one of which is the use of Viedma ripening, a relatively modern method that has been more extensively developed only in the last few decades. In this thesis, I aimed to demonstrate whether mechanical attrition in solution alone can induce the transformation of an initially racemic mixture of sodium chlorate into an enantiomerically pure phase. The results showed that the racemic system can gradually evolve into a single chiral phase, with the direction of chirality being random. I found that the dynamics of the process is strongly influenced by mixing intensity, sample purity, and the prevention of evaporation. Although cases of enantiomeric purity were observed, the outcomes were not sufficiently reproducible to reliably confirm the method under the laboratory conditions employed. Nevertheless, the study highlights the potential of Viedma ripening as an effective approach to obtaining enantiomerically pure crystals, with possible broader applications in chirality research and the development of new materials.
