Hello, I'm Dr. Emily, a chemist with expertise in the physical properties of materials. I've been researching and teaching about the fascinating world of chemicals for over a decade, and I'm happy to help you understand the behavior of rubbing alcohol in a freezer.

Let's talk about the freezing point of rubbing alcohol, which is also known as isopropyl alcohol. This particular type of alcohol has a freezing point of -89°C (-128°F).

Now, consider your freezer's temperature. Most standard home freezers operate at a temperature between -18°C (0°F) and -23°C (-10°F). As you can see, this is significantly higher than the freezing point of rubbing alcohol. Therefore, **rubbing alcohol will not freeze in a standard home freezer**.

However, if you were to use an extremely low-temperature freezer (also known as an ultra-low freezer) that can reach temperatures below -89°C (-128°F), you could technically freeze rubbing alcohol. But even then, the results might not be what you expect.

Here's why:

* Freezing Point Depression: Rubbing alcohol is usually not pure isopropyl alcohol but contains a small percentage of water. This water content will affect the freezing point of the solution. Due to a phenomenon called freezing point depression, the presence of water in the mixture lowers the freezing point compared to pure isopropyl alcohol. This means that the mixture will take a lower temperature than -89°C to completely freeze.
* Evaporation: Isopropyl alcohol is highly volatile, meaning it readily evaporates at room temperature. In a freezer, the low temperature would further slow down the evaporation rate, but it would still occur. This could lead to a decrease in the volume of the rubbing alcohol over time.
* Safety: Isopropyl alcohol is flammable, and while storing it in a freezer won't inherently make it more dangerous, it's important to be aware of the potential for fire hazards if the alcohol were to accidentally leak out of its container.

**In conclusion, while you can technically freeze rubbing alcohol in an ultra-low freezer, it's not recommended for practical purposes due to the freezing point depression and potential for evaporation. Additionally, always ensure proper safety measures when dealing with flammable substances.**

Grab a clean and dry used freezer bag, and fill it halfway with 3 parts water and 1 part rubbing alcohol. Seal the bag closed, and put it in the freezer. It will freeze into an ice pack, but it will still be malleable because of the rubbing alcohol.read more >>
