WebPresentation: To demonstrate crystallization, place a few crystals of sodium acetate trihydrate into a 250 mL beaker and pour the solution onto the crystals. Do not do this too slowly, since solid may start to form at the neck of the flask, eventually clogging it. Crystallization begins immediately forming a mound of white solid sodium acetate ... Crystallization is the process by which solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Attributes of the resulting crystal depend largely on factors such as temperature, air pressure, and in the case of liquid crystals, time of fluid WebCrystallization generally occurs by reducing the solubility of a solute in a solution by one or a combination of these four methods.
