It takes longer for the distilled water to start to freeze, but once it does freeze, it freezes rapidly. The ice crystals are not formed evenly. In the distilled water, the ice crystals can form around a scratch or bump in the ice tray forming a cone like a volcano with water in the middle.
Because distilled water is just water without sediment, it freezes at the same temperature: 0 degrees C. The amount of time it takes for the water to freeze depends on the temperature of the freezer, temperature of the water and amount of water in the container. For example, warmer water takes longer to reach the proper temperature than cooled water. It is also important not to overfill the tray – the water expands as it freezes so it needs room for this. And of course, make sure the tray is placed level in the freezer so as to prevent spillage.
Thomas and his team have learned that dissolving certain substances in water can affect nucleation, and hence freezing. As expected, they found that sea salt inhibits nucleation, meaning that it lowers the freezing temperature, but surprisingly they found that another type of salt – ammonium sulphate – enhances it, meaning it raises the freezing temperature.
Thomas Whale, from the University of Leeds, explains how freezing water works. First, it usually requires small particles of another solid to be present. “Contrary to popular perception, pure liquid water does not usually freeze at its melting point, 0°C, and can instead supercool to temperatures as low as -38°C. For ice formation to occur at relatively warm temperatures above -20°C a heterogeneous substance (a solid particle), called a nucleator, is required to trigger the initial nucleation event that must precede growth of ice crystals. Examples of nucleators include mineral dusts and biological substances.”
There are several reasons why this matters to scientists. Firstly, it’s important to the study of cloud formation, particularly for mixed phase clouds – that is clouds consisting of a mixture of water droplets and ice crystals. These types of clouds can form at temperatures between 0 and -40°C, and are particularly dominant in the Arctic.
Chemical Science is the flagship journal of the Royal Society of Chemistry and publishes findings of exceptional significance from across the chemical sciences. It is a global journal for the discovery and reporting of breakthroughs in basic chemical research, communicated to a worldwide audience without barriers, through open access. All article publication charges have been waived, meaning that the journal is free to read and free to publish.
As we near the end of winter in the UK it’s time to say goodbye to the gritter lorries – big yellow trucks, often with whimsical names, that patrol the nation’s main roads on icy nights. They spread a mixture of rock salt and crushed up grit. The grit provides extra grip for car tires, while the salt actually lowers the melting point of water, making it less likely to freeze.

FAQ
Is distilled water still good after freezing?
Is distilled water clear if you freeze it?
Does distilled water freeze different?
Is distilled water safe to make ice?
Why does distilled water freeze so hard?
Strong hydrogen bonds allow for the water to freeze harder. Freezes completely clear if no air bubbles are present and if using distilled water with TDS of 0ppm. What’s The Freezing Temperature Of Distilled Water? The freezing temperature of distilled water is typically 0°C (32°F). But, there are factors that lower the freezing point of it.
Can one use regular boiled water instead of distilled water?
Microorganisms may die during the boiling process, but minerals and particles will still be present, which is not a problem for ingestion.
What temperature does distilled water freeze?
The freezing temperature of distilled water is typically 0°C (32°F). But, there are factors that lower the freezing point of it. These include the temperature of the freezer, the temperature of the water, and traces of salts in the water. How Long Does It Take For Distilled Water To Freeze?
How does freeze distillation work?
Freeze distillation is a method of distilling alcohol simpler than you would if you were using distilling equipment. This is the most traditional method. It works by lowering the temperature (freezing) of your alcoholic beverage, and the liquid with the lowest freezing point (ethanol) melts more quickly than water.
