Crystallization of Supersaturated Sodium Acetate - Commercial Application
Now a commercial application of this crystallization process is shown. A metal disc is manipulated inside a sealed plastic bag holding the sodium acetate solution. This causes the sodium acetate to crystallize. The digital thermometer shows that the temperature of the heating pack has gone up significantly from room temperature. This heating pack provides an easily portable method of having heat available whenever and wherever it is needed.
