What is the hot ice?
Hot ice may refer to: In chemistry: Sodium acetate, a salt commonly used in a supersaturated solution with water to produce heat and salt crystals, which resemble ice.
Instant Hot Ice works through a supersaturated solution of sodium acetate trihydrate and water. Once cooled, the solution becomes unstable and can easily be triggered into a hot mass of ice. The release of the sodium acetate trihydrate molecules from the water triggers an exothermic reaction, the heat you feel.
- Supersaturation is a state of a solution that contains more of the dissolved material than could be dissolved by the solvent under normal circumstances. It can also refer to a vapor of a compound that has a higher (partial) pressure than the vapor pressure of that compound.

- Let's imagine we're talking about a solid dissolved in a liquid. A saturated solution can become supersaturated when it is cooled. The solubility of solid solutes in liquid solvents increases as the solvent is warmed up. For example, you can dissolve more sugar in warm water as opposed to cold water.
Things You'll Need
- Sodium acetate trihydrate (or white vinegar and baking soda)
- Medium to large pot (steel or Pyrex)
- Clean container.
- Ice bath (or refrigerator)
- Water at a very high pressure turns to ice even though it can be quite hot. Water becomes a solid at room temperature at about 30,000 atmospheres. If you increase the pressure, you can increase the temperature and have it remain ice. It isn't quite the same as the ice you are used to, but it is a solid.
- Ways to make a saturated solution include: Add solute to liquid until dissolving stops. Evaporate a solvent from a solution until the solute begins to crystallize or precipitate.
- Examples of Unsaturated Solutions. The solvent for the ocean is water, a liquid, and salt is the solute. We have all had iced tea, and we all know someone who likes a lot of sugar mixed in their tea. An unsaturated tea and sugar solution would be one into which you could add more sugar and have the sugar still dissolve
'Hot Ice' Is A Thing: Watch What Happens When This Guy Puts His Hand In It. Sodium acetate trihydrate, commonly referred to as “hot ice,” may seem like a dangerous chemical, but in reality it can be produced in your kitchen using vinegar and sodium bicarbonate (baking soda), and poses you no threat.
- Sodium Acetate Crystallization. If disturbed, or a tiny sodium acetate crystal is introduced into the solution, the oppositely charged ions (CH3–COO– and Na+) form a solid crytal structure quickly. The process is exothermic, releasing heat energy, which explains why this process is commonly referred to as "hot ice".
- Because the solute in a supersaturated solution is present in a concentration higher than the equilibrium concentration, supersaturated solutions are unstable.
- This is because heated water molecules move farther apart, making room for more solid substance to dissolve. When no more of the solid substance can be dissolved, the solution is said to be saturated. Crystals begin to form and build on one another as the water lets go of the excess solute.
