Uses[change | change source]

On concrete[change | change source]

Sodium acetate is used to reduce the effects of water damage to concrete. It does this by acting as a concrete sealant. Compared to epoxy, which is commonly used, sodium acetate is cheaper and does not damage the environment.

Preparation[change | change source]

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.
