Sodium acetate trihydrate crystals melt at 58–58.4 °C (136.4–137.1 °F), [12] [13] and the liquid sodium acetate dissolves in the released water of crystallization. When heated past the melting point and subsequently allowed to cool, the aqueous solution becomes supersaturated. This solution is capable of cooling to room temperature ...
