Does Distilled Water Freeze? (Clear or Not Clear)

Interestingly, water can be molded in different types just by simple processes like boiling. Distilled water is also a type of water which is produced simply by boiling water. Once it reaches the boiling temperature, steam is formed which is then condensed back into a liquid form.

Ideally, distilled water is free from impurities, in fact, even the minerals are removed which is why it is also considered as the purest form of water.

Distilled water is used for different purposes including:

  • Sterilization of medical equipment
  • Used in batteries
  • Other applications where mineral-free water is required

Since distilled water is the purest form of water, it leads to the question, does distilled water freeze?” Let’s find out.

What’ll You Learn

  • Does distilled water freeze?
  • Does distilled water freeze clearer and faster compared to salt water?
  • What is the freezing point of distilled water?
  • Does distilled water freeze in car batteries when exposed to extreme temperatures?

Lets reiterate the first question, does distilled water freeze? Yes, distilled water can be frozen. There is a wide misconception with distilled water that it cannot be frozen, however, it is certainly not true.

Does distilled water freeze?

In fact, distilled water can be frozen. Just like tap water or salt water, distilled water too has a specific freezing point.

To help you understand this better, let’s consider the freezing point of water. Technically speaking, the freezing point of water depends on the amount of foreign particles or impurities in it.

In other words, when water is not filtered completely and has impurities in it, it may freeze slightly slower. This is because when water reaches freezing temperature the impurities or foreign particles can interfere with crystal lattice of the ice.

In that case, the temperature needs to be lowered further. Now looking at the composition of distilled water, it is free from the extraneous particles. Due to this, it is easier to reach the freezing point of distilled water as compared to tap water which takes slightly more time.

Summing up, yes, distilled water can be frozen!

Does Distilled Water Freeze Clear?

No, distilled water does not freeze entirely clear on its own. Although it may freeze clearer compared to tap or salt water, but it certainly does not freeze 100% clear. The reason behind this is that there are small air bubbles trapped in water during the process of freezing.

Despite using distilled water, air bubbles will still end up getting stuck in the ice. Usually, when water begins freezing, it freezes from the outer layers which pushes the air bubbles to move to the center, which results in cloudy ice.

Simply put, greater the amount of air bubbles in the water, the cloudier the ice will be.

For getting a completely clear ice, there are two pre-requisites. One, the water must be distilled, second, the water must be boiled twice. Start by boiling the water once, then let it cool off completely. Make sure to cover it so that no impurities like dust can enter the water.

After the water is cooled off, remove the lid and boil the water again. Let it cool off and ensure that it is at room temperature before storing it in the freezer or an insulated cooler to begin the process of freezing.

Doing this will allow you to completely eliminate the air bubbles from the water which will ultimately result in a much clearer ice from the distilled water.

What Temperature Does Distilled Water Freeze?

Depending on whether the distilled water is complete free from impurities, it will freeze at a temperature below zero around the 2 – 3 degree mark. At 0 degrees the process of freezing will be concluded.

To further add, if there are impurities in the distilled water  the freezing temperature of the distilled water will be pushed back. The impurities can either be in the form of air bubbles, dust particles, and contaminants in the container.

In case of impurities, the freezing points will be pushed back, and freezing will begin at negative temperatures.

Does Distilled Water Freeze Faster?

As mentioned earlier, the rate of freezing of water depends on the number of impurities in the water. In the case of distilled water, it is up to 99.99% free from impurities and even the minerals are removed.

Since distilled water is a much purer form of water, it freezes faster compared to regular tap water or salt water.

Does Distilled Water Freeze In Batteries?

No, distilled water does not freeze easily in batteries as long as the batteries are fully charged. For a fully charged battery containing distilled water to freeze, the temperature must reach over – 76 degrees F.

Technically speaking, the electrolytic solution of a battery contains sulfuric acid and distilled water in a ratio of 25:75 respectively. In simpler terms, it contains 25% of the acid, whereas the rest is water content.

Now, when a battery is charging, the acid and water content in the battery undergoes a chemical reaction. Due to this, the liquids are mixed which increases their resistance against freezing.

To conclude, if a battery is fully charged or plugged in for charging, it will not freeze. However, if the battery is discharging, it will ultimately freeze when exposed to freezing temperatures.

Is Freezer Ice Distilled Water?

Is Freezer Ice Distilled Water?

Simply put, no! Freezer ice is not distilled water. Many people are under the influence that freezer ice or melted ice water is distilled water. But it is certainly not true.

Water can only be converted into a distilled form using the process of boiling, evaporation, and condensation. This is the only way to get distilled water and simply freezing and collecting the melted water won’t do the trick.

Is Distilled Water Harder To Freeze?

Freezer Ice Distilled Water

No, distilled water is not hard to freeze. The reason behind this is that distilled water is 99.99% pure and contains relatively no impurities or contaminants which are usually the limiting factors when freezing water.

On the contrary, tap water and salt water has a high concentration of minerals and impurities, which makes it difficult to freeze tap water and salt water. 

Conclusion – Does distilled water freeze?

Distilled water can be frozen just like tap water and salt water. In fact, distilled water can freeze more quickly compared to tap water and salt water. This is because distilled water is essentially free from impurities and contaminants.

Furthermore, freezing distilled water will also result in much clearer ice due to the fact that there are no impurities in it.


This is my blog about the ways and solutions that can help you improve your health by taking more value from drinking water. As improving health means a lot to me, I decided to create the Water On Top project with the purpose to reveal the benefits of water, the finest products to take our daily water to another level, and much more great stuff about water that I believe is on top of our nutrition.
