HOW SODIUM ACETATE (ANHYDROUS AND TRIHYDRATE) IS MADE:
Sodium Acetate (anhydrous and trihydrate) is prepared by reacting either sodium hydroxide (NaOH) or sodium carbonate (Na2CO3) with acetic acid (HC2H3O2).
With sodium hydroxide, for example, the reaction is:
NaOH + HC2H3O2 → NaC2H3O2 + H2O

SOLUBILITY OF SODIUM ACETATE (ANHYDROUS AND TRIHYDRATE):
Sodium Acetate (anhydrous and trihydrate) is very soluble in water; soluble in ether; slightly soluble in ethyl alcohol
The Sodium Acetate (anhydrous and trihydrate) forms as the trihydrate, which is then recovered by evaporating the reacting solution.
The anhydrous salt can be prepared by heating the hydrate to drive off the water of hydration.

PREPARATION OF SODIUM ACETATE (ANHYDROUS AND TRIHYDRATE):
For laboratory use, Sodium Acetate (anhydrous and trihydrate) is inexpensive and usually purchased instead of being synthesized.
Sodium Acetate (anhydrous and trihydrate) is sometimes produced in a laboratory experiment by the reaction of acetic acid, commonly in the 5–18% 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 (anhydrous and trihydrate) 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 the 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 (anhydrous and trihydrate) trihydrate is prepared by reacting acetic acid with sodium hydroxide using water as the solvent.
CH3COOH + NaOH → CH3COONa + H2O.

To manufacture anhydrous Sodium Acetate (anhydrous and trihydrate) industrially, the Niacet Process is used.
Sodium metal ingots are extruded through a die to form a ribbon of sodium metal, usually under an inert gas atmosphere such as N2 then immersed in anhydrous acetic acid.

2 CH3COOH + 2 Na →2 CH3COONa + H2.
The hydrogen gas is normally a valuable byproduct.

STRUCTURE OF SODIUM ACETATE (ANHYDROUS AND TRIHYDRATE):
The crystal structure of anhydrous Sodium Acetate (anhydrous and trihydrate) has been described as alternating sodium-carboxylate and methyl group layers.
Sodium Acetate (anhydrous and trihydrate) 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

REACTIONS OF SODIUM ACETATE (ANHYDROUS AND TRIHYDRATE):
Sodium Acetate (anhydrous and trihydrate) can be used to form an ester with an alkyl halide such as bromoethane:
CH3COONa + BrCH2CH3 → CH3COOCH2CH3 + NaBr

Sodium Acetate (anhydrous and trihydrate) 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. Cesium salts also catalyze this reaction.

THE INTERESTING FACTS OF SODIUM ACETATE (ANHYDROUS AND TRIHYDRATE):
In 1995, officials in Michigan tested Sodium Acetate (anhydrous and trihydrate) trihydrate as a deicing salt for airport runways.
Experiments showed, however, that the anhydrous salt worked better than the trihydrate for this purpose.
Sodium Acetate (anhydrous and trihydrate) has also been used as a deicer in parking garages.

Sodium Acetate (anhydrous and trihydrate) is preferred to sodium chloride, widely used as a deicing compound, because sodium chloride corrodes steel rods buried in concrete and Sodium Acetate (anhydrous and trihydrate) does not.
Heat packs sometimes contain a solution of Sodium Acetate (anhydrous and trihydrate) trihydrate cooled below its freezing point.

When the pack is activated, the compound freezes very rapidly, releasing the heat that had been stored in its supercooled phase.
cosmetics industry uses Sodium Acetate (anhydrous and trihydrate) as a buffering agent in a variety of personal care products.

A buffering agent, Sodium Acetate (anhydrous and trihydrate), is a substance that maintains the acidity of a product within a certain desired range.
Sodium Acetate (anhydrous and trihydrate) is also used by food producers for the same reason, assuring that a variety of foods have an acidity sufficient to protect the food from decaying, but not so acidic as to have an unpleasant taste.
