Abstract: Dissolution, crystallization and crystal cultivation are fundamental operations in the experiments of solution preparation, chemical synthesis, separation and purification. These are essential techniques for students in chemistry-related majors. This paper introduces the methods of these operations, outlines the related operation standards, and emphasizes the key precautions based on some practical cases.

Key words: Dissolution, Crystallization, Crystal cultivation, Single crystal, Operation standards
