Hot ice is a fascinating substance that has many unique properties. It’s also known by a few other names, including dry ice and carbon dioxide snow. But what is hot ice exactly? And how does it work?
Hot ice is a type of sodium acetate that has been cooled below its melting point. This makes the liquid crystallize, which causes the ice to become hot. The crystallization process is exothermic, so the resulting ice is hot.
Hot ice is a useful chemical for many purposes. It can be used to cool things down, or to keep things hot. It can also be used to create interesting effects, like when it is used to make hot ice cream.
Hot ice is made by combining baking soda and vinegar. This creates a chemical reaction that results in the formation of sodium acetate. The sodium acetate is then cooled below its melting point, which causes it to crystallize.
The process of making hot ice is simple, but it does require some care. Make sure to follow the instructions carefully and be careful not to touch the hot ice with your skin.

How does hot ice work?
Sodium acetate exists as a supercool liquid in the fridge, meaning that it is in liquid form below its usual freezing point. As soon as it is disturbed it starts to crystallise. The crystallisation is an exothermic reaction which is why we call it hot ice!
The process of making hot ice is actually quite simple. All you need is a solution of sodium acetate and water. When you heat this solution, the sodium acetate dissolves and forms a supercooled liquid. This liquid can then be poured into moulds to form shapes.
Once the hot ice has cooled and hardened, you can then touched or even hit it without it breaking. However, if you disturb it too much, it will start to crystallise. The beauty of hot ice is that you can control when it crystallises by simply touching it lightly.
Why is it called Hot Ice?
Sodium acetate trihydrate is a substance that looks like ice crystals at room temperature. If heated, it starts turning into a transparent liquid. Since the ice like crystals are formed at a relatively hotter temperature than water-ice, it is called hot ice.
Hot ice is used in a variety of ways. It can be used as a coolant for food or as a heat sink for electronic components. It is also used in cryogenics and in emergency de-icing of roads and walkways.
The most common use for hot ice is in science demonstrations. When sodium acetate is mixed with water, it breaks down into sodium ions and acetate ions. These ions are attracted to each other and form crystals. The crystals grow until they become too big to stay suspended in the liquid. As the crystals fall to the bottom of the container, they release heat.
This process is called endothermic crystallization. The heat released by the falling crystals melts the remaining water in the solution. This creates a supersaturated solution that is unstable. When a seed crystal is added, the solution suddenly becomes saturated and the excess liquid crystallizes out.
The resulting solid is brittle and easily broken. However, when placed in water, it will quickly reform into a stable configuration. This makes hot ice a fun and safe substance to play with.
Is Hot ice actually ice?
Hot ice is not real ice! Normal ice: is made from freezing water at freezing point temperatures (what is H2O? H2O is a molecule made of 2 hydrogen atoms and 1 oxygen atom. That’s it. Just those 3 atoms.
Hot ice: is made from freezing water at subzero temperatures. The colder the temperature, the more energy the water molecules have. And when those water molecules have a lot of energy, they can break the bonds that hold them together.
Hot ice is really just frozen water that has broken its bonds. It’s not actually ice, it’s just water that looks like ice.
But even though it’s not really ice, hot ice can still be used in all the same ways as regular ice. You can use it to cool drinks, keep food cold, or even make sculptures!
What is another name for Hot ice?
Sodium acetate, also known as hot ice, is a salt with a variety of uses. As an isolated compound, it is often used as a food preservative or as a deicer. When dissolved in water, it can be used to create a hot ice bath for cooking or as a heat pack.
Sodium acetate is the sodium salt of acetic acid. It has a mild, acetic acid taste and is hygroscopic (absorbs moisture from the air). It is soluble in water and insoluble in most organic solvents.
When heated above its melting point (58 °C), sodium acetate forms a eutectic mixture with water (40% by weight sodium acetate and 60% by weight water). This mixture is referred to as “hot ice” because it appears to be smoking while remaining at a constant temperature.
Sodium acetate can be used as a heat pack when dissolved in water. When the solution cools, the resulting sodium acetate trihydrate crystals have a high heat of fusion, allowing them to store heat efficiently.
The trihydrate form of sodium acetate is sometimes used as a food additive. It acts as a preservative and can also be used to control the pH of foods.
What temperature is hot ice?
Hot ice is a substance called sodium acetate trihydrate. It solidifies at room temperature, melts into a liquid at 58 degrees Celsius, and can also be supercooled into a liquid below its freezing point.
Sodium acetate trihydrate is an ionic compound with the formula Na3C6H5(OOCCH3)3.3H2O. It is the sodium salt of acetic acid and occurs as a white deliquescent powder that absorbs moisture from the air.
When heated above 58 °C, sodium acetate trihydrate crystals dissociate into sodium acetate and water. The resultant solution is called “hot ice solution” and is capable of depositing crystals of sodium acetate upon cooling. This process is reversible, allowing “hot ice” to be made by dissolving sodium acetate in water and then cooling the solution. The solution can be supercooled below its melting point so long as it is not agitated, in which case crystallization will occur spontaneously.
“Hot ice” has been used for many years as an analog computer memory device. When a crystal of sodium acetate is deposited, it can be used to store a bit of digital information. By heating the crystal, the information can be erased and the crystal can be reused.
“Hot ice” has also been used as a refrigerant. When heated, it absorbs heat from its surroundings and when cooled, it releases that heat. This makes it ideal for use in thermal energy storage. Sodium acetate can store large amounts of heat for extended periods of time, making it suitable for use in solar power plants, where it can store heat collected during the daytime for use at night.
