Webtechnically refer to different processes. Crystallization refers to the formation of a new, insoluble product by a chemical reaction; this product will then precipitate out of the reaction solution as an amorphous solid containing many trapped impurities. Typically, crystallization is the method used to obtain the crude product. WebCrystallization is a technique that has long been used in the purification of substances. Often, when a solid substance (single compound) is placed in a liquid, it dissolves. Upon … WebThis affords a practical method of obtaining solid chemicals in a pure form suitable for handling, storing, and marketing.
