Applications of Sodium Acetate
 
01/

Biotechnological
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.

02/

Biotechnological
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.

03/

Concrete Longevity
Sodium acetate is used to mitigate water damage to concrete by acting as a concrete sealant, while also being environmentally benign and cheaper than the commonly used epoxy alternative for sealing concrete against water permeation.

04/

Food
Sodium acetate may be added to food as a seasoning, sometimes in the form of sodium diacetate, a one-to-one complex of sodium acetate and acetic acid, given the E-number E262. It is often used to give potato chips a salt and vinegar flavour, and may be used as a substitute for vinegar itself on potato chips as it doesn't add moisture to the final product. Sodium acetate (anhydrous) is widely used as a shelf-life extending agent and pH control agent. It is safe to eat at low concentration.

05/

Buffer Solution
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).

06/

Heating Pad
Sodium acetate is also used in heating pads, hand warmers, and hot ice. A supersaturated solution of sodium acetate in water is supplied with a device to initiate crystallization, a process that releases substantial heat.

Enhancing Sour Taste
Sodium acetate trihydrate can provide a tangy flavor to foods, especially snacks, sauces, condiments, pickles, and cheese. It can also mask unpleasant tastes or odors in some foods.

Adjusting Ph
Sodium acetate trihydrate can act as a buffer to maintain a stable pH in foods, especially acidic or alkaline foods. It can also neutralize excess acidity or alkalinity in foods, which can affect the texture, color, or shelf life of foods.

Preserving Food
Sodium acetate trihydrate can inhibit the growth of bacteria, molds, and yeasts in foods, especially meat, fish, dairy, and fruit products. It can also prevent oxidation and browning of foods, which can affect the quality and appearance of foods.

Safe Food Additives
Sodium acetate trihydrate is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). The acceptable daily intake (ADI) for sodium acetate (anhydrous or trihydrate) is not specified by the Joint FAO/WHO Expert Committee on Food Additives (JECFA), which means that it can be consumed at levels normally found in foods.

 

How to Use Sodium Acetate Trihydrate Safety:

Here are some tips on how to use sodium acetate trihydrate safely:

1)Wear protective gloves, goggles, and clothing when handling sodium acetate trihydrate. Avoid direct contact with the skin, eyes, and mucous membranes.
2)Store sodium acetate trihydrate in a cool, dry, and well-ventilated place. Keep it away from heat, sparks, flames, and other sources of ignition.
3)Do not ingest sodium acetate trihydrate. If swallowed, rinse the mouth with water and seek medical attention immediately.
4)Do not inhale sodium acetate trihydrate. If inhaled, move to fresh air and seek medical attention if symptoms persist.
5)Do not dispose of sodium acetate trihydrate in the drain or the environment. Follow the local regulations for waste disposal.
6)Read the label and the safety data sheet (SDS) of sodium acetate trihydrate before using it. Follow the instructions and warnings carefully.

How to Store Sodium Acetate Trihydrate
 

Industrially, sodium acetate trihydrate is prepared by reacting acetic acid with sodium hydroxide using water as the solvent. Therefore, it is important to store trihydrate sodium salt properly to prevent it from losing its water of crystallization and becoming anhydrous sodium acetate, which has different properties and applications.

 

Keep It in a Sealed Container
The best way to store trihydrate sodium salt is to keep it in a sealed container in a cool, dry and dark place. The container should be made of glass, plastic or metal that does not react with the salt or the moisture. The container should also be labeled with the name, formula, CAS number and hazards of the salt. The storage temperature should be below 58 °C (136 °F), which is the melting point of trihydrate sodium salt. The storage humidity should be below 65%, which is the relative humidity at which the salt starts to deliquesce.

 

Don't Expose It to High Temperature Or Humidity
If the trihydrate sodium salt is exposed to high temperature or humidity, it may melt, liquefy or solidify into a hard mass. This can make it difficult to use or measure accurately. If this happens, the salt can be restored by heating it gently in an oven or a water bath until it melts completely, then cooling it slowly in a desiccator or an airtight container until it crystallizes again. Alternatively, the salt can be dissolved in water and then recrystallized by evaporating the water.

 

Frequently Asked Questions about Trihydrate Sodium Salt
 

Q: What is sodium acetate (trihydrate)?

A: Acetic acid has been said to prevent bacteria cultivation and therefore has been used not only to add sour taste but to preserve food. Sodium acetate is a food additive obtained by neutralization of acetic acid. When used as a food additive, sodium acetate can be indicated by its group name, substance name or abbreviated name according to the purpose of use.

Q: What is the names of trihydrate sodium salt?

A: Preferred IUPAC name: Sodium acetate Other names: Hot ice (sodium acetate trihydrate)

Q: Is sodium acetate in food safe?

A: It is highly safe and its use is not restricted. Sodium acetate can prevent bacteria cultivation in a wide range of acidic region. It also functions as a buffer as well. When used to add sour taste to food, acetic acid is generally selected, but combination of sodium acetate and acetic acid can make the taste mild.

Q: What the industrial uses of sodium acetate?

A: 1) Cleaning
Impurities such as stains, rust, or scale on metal surfaces quickly vanish when with cleaning sodium acetate. 
2)Concrete
Hygroscopic sodium acetate seeps into the crevices on the surface of concrete, sealing it against the elements. Water damage is the scourge of the construction industry's concrete usage, and the ability to seal concrete against water saves time and money.
3)Food and Beverage
Sodium acetate has long been the seasoning that gives potato chips that pungent salt and vinegar flavor. Because it is an acid, the addition of sodium acetate during food production can lower or stabilize a product's pH. Another positive trait of its acidity is the negative reaction of bacterial growth in the presence of sodium acetate. It is, therefore, a great preservative. The beneficial preservation properties of sodium acetate are also dominant in pickling foods. Similar to general food use, pickling uses sodium acetate to enhance flavors and preserve foods, but in much larger quantities. 
4)Laboratory
The growth of bacteria often requires a source of carbon. Sodium acetate fills that role while also catalyzing ethanol precipitation yield when isolating DNA. Sodium acetate is commonly used as a reagent in molecular biology as well as biochemistry. 
5)Medical
An intravenous transfusion of sodium acetate is recommended for electrolyte replenishment. This occurs frequently with patients undergoing dialysis. Hyponatremic patients are often given sodium acetate to stabilize falling sodium levels. Reusable heating pads and hand warmers rely on a supersaturated solution of sodium acetate and water surrounding a metal disc.
