Heating pad [ edit ] A hand warmer containing a supersaturated solution of sodium acetate which releases heat upon crystallization Sodium acetate is used as the carbon source for culturing bacteria. Sodium acetate is also useful for increasing yields of DNA isolation by ethanol precipitation.

The crystal structure of anhydrous sodium acetate has been described as alternating sodium-carboxylate and methyl group layers. [18] Sodium acetate trihydrate's structure consists of distorted octahedral coordination at sodium. Adjacent octahedra share edges to form one-dimensional chains. Hydrogen bonding in two dimensions between acetate ions and water of hydration links the chains into a three-dimensional network.

A supersaturated solution of sodium acetate in water is supplied with a device to initiate crystallization, a process that releases substantial heat.Industrially, sodium acetate trihydrate is prepared by reacting acetic acid with sodium hydroxide using water as the solvent. a b Acetic acid, sodium salt in Linstrom, PeterJ.; Mallard, WilliamG.
