Crystallization of sodium acetate

Crystallization of sodium acetate. When solid sodium acetate trihydrate (CH3COONa 3H2O) melts at 58C, it releases bound water (water of crystallization) and dissolves in it. When the solution is then allowed to cool slowly, it becomes supersaturated. When a nucleation centre (a small piece of solid sodium acetate) is introduced, it causes the solution to crystallize back into solid sodium acetate trihydrate. This process is exothermic and releases heat. It found its use in consumer heating pads.
