The Anhydrous is normally a powder while the Trihydrate is typically a granular crystal. Also, the Trihydrate is very soluble in water compared to the anhydrous version. The anhydrous offers different characteristics including low dustiness, higher reactivity, higher density, and improved free-flow-ability. The molecular weight of the Trihydrate is 136.08 g/mol compared to the anhydrous at 82.04 g/mol. The Cas No for Sodium Acetate Anhydrous is 127-09-03, the Trihydrate is identified by CAS No. 6131-90-4

Is Sodium Acetate Dangerous

In general Sodium Acetate is a fairly safe chemical, in fact, it is on the FDA's list of Generally Recognized as Safe (Gras) chemicals. In relatively small levels it is benign in the environment, and not considered harmful.

In fact, it is a major component of Sodium diacetate that is a very common preservative and flavor enhancer used in many foods. It is however considered to be an eye and a little bit of a skin irritant in some situations.

The other caution is that Sodium Acetate can be flammable if brought into contact with open flames, it also reacts if mixed with oxidizers such as nitrc acid or potassium nitrate.

How Long can you Keep Sodium Acetate

Sodium Acetate, if stored in ideal storage conditions can last anywhere from 2 to 4 years or more. It is best to keep it dry, cool and out of the sun, an airtight container would work great. Regular testing after the 2 years will ensure the sodium acetate still works well in your application. However if at all possible it is best to only purchase quantities that will be used in 2 years to ensure ideal performance.

How is Sodium Acetate Made

Sodium acetate is manufactured by reacting acetic acid (vinegar) with sodium hydroxide. There are other manufacturing methods including using sodium carbonate instead of the sodium hydroxide. A manufacturer could even create sodium acetate by combining vinegar and sodium bicarbonate (baking Soda)

You can actually make sodium Acetate at home using Baking Soda, Vinegar, Coffee Filters and a spoon. Your results may vary and we suggest caution but you can find more information on making sodium acetate here

Sodium Acetate Uses

Sodium acetate is commonly used to help increase the life of concrete through helping to seal it against water permeation. It has been used as a substitute for the epoxy to this ends.

Also commonly used with Acetic Acid to act as a buffer to maintain a consistent pH level between 4 -6.

It is also commonly used in the tanning, to increase the penetration of the dyes and tanning products. It also helps to increase the rate at which the tan is absorbed.

In the TEXTILE industry, sodium acetate is considered a dye and color intermediate, with specific use as a mordant in the dyeing process, it is also used in the in textile industries to neutralize sulfuric acid waste streams. Because of its ability to remove insoluble calcium salts, sodium acetate is further used by the textile industry to improve the wearing quality of finished fabrics.

It is also commonly used in the petrochemical industries.

If you want to make your own hot ice you will need Sodium Acetate as it is a major ingredient. You can find a formula to make hot ice below.

It is also commonly used as a polymerization catalyst and in detergents, for its thermal energy storage characteristics, You can find Sodium Acetate used in conjunction with Sodium Diacetate to increase flavors of various foods.

Is Sodium Acetate Natural?

Sodium Acetate is a salt of Acetic Acid and sodium hydroxide. Acetic acid is an organic compound, so it really depends on if the individual would consider it natural in that circumstance. Acetic acid is products naturally as fruits begin to spoil.

How to Use Sodium Acetate for Dry Ice

What you need to do is saturate the water with sodium acetate at a high temperature. There are 2 ways of getting this.

Heat water to about 60 deg C, then add sodium acetate until it will no longer dissolve. Pour the liquid into a vessel, making sure you DO NOT transfer any solid into the vessel. Stick the solution into the fridge until it is cooled to fridge temperature or even room temperature. At this point, the solution is supercooled, and any trigger can induce crystallization.

Make a saturated solution of sodium acetate at room temperature (i.e. add acetate until you are left with an undissolved layer). Heat the solution to 60 deg C, which causes the remainder to dissolve. Once the solution is completely clear, pour it into a vessel and stick it in the fridge, as in method 1.

Method 1 will give you more crystals when touched, but any solid transferred will ruin the experiment. Method 2 will always work but generates fewer crystals.

There are no other specifics. You need to make a supersaturated solution, and can not transfer any solid material from the saturate.

How to Make Hot Ice With Sodium Acetate

Things You'll Need:

  • Sodium acetate
  • Small sauce pan
  • Water

Fill a saucepan will water and heat it until it is near-boiling. Boiling is too hot, but a small amount of simmering is okay. The main thing is to make the water hot.

Dissolve as much sodium acetate into the water as possible. The more you dissolve into the water, the denser the crystals will be when they form the hot ice. Keep stirring in as much as possible until you can no longer get the sodium acetate to dissolve in the water. It is important to stir the mixture constantly at this stage.

Know that when the mixture is completely dissolved, pour it into a glass or other container. Make sure to only pour the water with dissolved sodium acetate into the glass. If any sodium acetate remains undissolved, leave it in the bottom of the pan as you pour.

Place the glass in your refrigerator to allow the water to cool.

Be aware that after the mixture has cooled, pour some into a tray, mold or whatever container you wish to hold the hot ice. As you pour it into the tray, note that it remains in liquid form.

Just touching the solution will not instigate the reaction, you must introduce a "seed" crystal. To do this, lightly moisten your fingertip so a couple of dry/un-dissolved crystals will stick there, now you're ready to touch the solution. Touch the top of the liquid with the tip of your finger. You do not need to dip your finger or hold it on the liquid. Just a quick tap is all that is needed. Hot ice crystals will instantly form where you touch and will spread through the mixture until every drop of liquid is in a frozen but hot crystalline state. In just one second you will have hot ice.
