While sodium acetate is usually purchased, it can be produced in the laboratory by the reaction of acetic acid with sodium carbonate, sodium bicarbonate, or sodium hydroxide.
Industrially, sodium acetate trihydrate is prepared by reacting acetic acid with sodium hydroxide using water as the solvent.
