Sodium acetate crystallization

Sodium acetate crystallization is a process where a supersaturated solution of sodium acetate transitions into solid crystals, often rapidly, upon triggering. This occurs because sodium acetate has a high solubility in water at elevated temperatures, allowing for supersaturation when cooled. Introducing a seed crystal or a disturbance initiates crystallization, releasing stored heat and forming a solid structure. This exothermic process is commonly used in hand warmers and educational demonstrations due to its dramatic and visually striking crystallization.
