Medically, sodium acetate is important component as an electrolyte replenisher when given intravenously.
Sodium Acetate is mainly indicated to correct sodium levels in hyponatremic patients.
Sodium Acetate can be used also in metabolic acidosis and for urine alkalinization

Sodium acetate, NaCH3COO, also abbreviated NaOAc, is the sodium salt of acetic acid.
This colorless deliquescent salt has a wide range of uses.

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.
Sodium acetate is used in the textile industry to neutralize sulfuric acid waste streams and also as a photoresist while using aniline dyes.

Sodium Acetate is often used to give potato chips a salt and vinegar flavor.
Sodium acetate (anhydrous) is widely used as a shelf-life extending agent, pH control agent
Sodium Acetate is safe to eat at low concentration.
A solution of sodium acetate (a basic salt of acetic acid) and acetic acid can act as a buffer to keep a relatively constant pH level.
This is useful especially in biochemical applications where reactions are pH-dependent in a mildly acidic range (pH 4–6).

Sodium acetate is also used in heating pads, hand warmers, and hot ice.
Sodium acetate trihydrate crystals melt at 136.4 °F/58 °C (to 137.12 °F/58.4 °C), dissolving in their water of crystallization.
When they are heated past the melting point and subsequently allowed to cool, the aqueous solution becomes supersaturated.
This solution is capable of cooling to room temperature without forming crystals.
By pressing on a metal disc within the heating pad, a nucleation center is formed, causing the solution to crystallize back into solid sodium acetate trihydrate.
The bond-forming process of crystallization is exothermic.
The latent heat of fusion is about 264–289 kJ/kg.
Unlike some types of heat packs, such as those dependent upon irreversible chemical reactions, a sodium acetate heat pack can be easily reused by immersing the pack in boiling water for a few minutes, until the crystals are completely dissolved, and allowing the pack to slowly cool to room temperature.

For laboratory use, sodium acetate is inexpensive and usually purchased instead of being synthesized.
Sodium Acetate is sometimes produced in a laboratory experiment by the reaction of acetic acid, commonly in the 5–8% solution known as vinegar, with sodium carbonate ("washing soda"), sodium bicarbonate ("baking soda"), or sodium hydroxide ("lye", or "caustic soda").
Any of these reactions produce sodium acetate and water.
When a sodium and carbonate ion-containing compound is used as the reactant, the carbonate anion from sodium bicarbonate or carbonate, reacts with hydrogen from the carboxyl group (-COOH) in acetic acid, forming carbonic acid.
Carbonic acid readily decomposes under normal conditions into gaseous carbon dioxide and water.
This is the reaction taking place in the well-known "volcano" that occurs when the household products, baking soda and vinegar, are combined.

CH3COOH + NaHCO3 → CH3COONa + H2CO3H2CO3 → CO2 + H2O
Industrially, sodium acetate trihydrate is prepared by reacting acetic acid with sodium hydroxide using water as the solvent.

CH3COOH + NaOH → CH3COONa + H2O

The crystal structure of anhydrous sodium acetate has been described as alternating sodium-carboxylate and methyl group layers.
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

Sodium acetate can be used to form an ester with an alkyl halide such as bromoethane:

CH3COONa + BrCH2CH3 → CH3COOCH2CH3 + NaBr
Sodium acetate undergoes decarboxylation to form methane (CH4) under forcing conditions (pyrolysis in the presence of sodium hydroxide):

CH3COONa + NaOH → CH4 + Na2CO3
Calcium oxide is the typical catalyst used for this reaction.
Caesium salts also catalyze this reaction

Sodium Acetate is a moderately water soluble crystalline Sodium source that decomposes to Sodium oxide on heating.
Sodium Acetate is generally immediately available in most volumes.
All metallic acetates are inorganic salts containing a metal cation and the acetate anion, a univalent (-1 charge) polyatomic ion composed of two carbon atoms ionically bound to three hydrogen and two oxygen atoms (Symbol: CH3COO) for a total formula weight of 59.05.
Acetates are excellent precursors for production of ultra high purity compounds, catalysts, and nanoscale materials.
