Why does antifreeze lower the freezing point of water?

WebThe freezing point of a solution is always less than the freezing point of the pure solvent due to disruption of intermolecular interactions. The freezing point of saltwater is thus lower than the freezing point of pure water. This means that adding ice to winter roads can help water melt. WebThe salt lowers the temperature at which water freezes, so with salt ice will melt even when the temperature is below the normal freezing point of water. This is an easy way to teach phase change.

Web9 jun. 2024 · BOILING & FREEZING POINTS Pure water, as you may know, has a boiling point of 212°F (100°C) and a freezing point of 32°F (0°C). However, when you create a 50/50 mixture using water and ethylene glycol, the boiling point rises to 223°F (106°C) and the freezing point lowers to -35°F (-37°C). WebWhen the ionic compound salt is added to the equation, it lowers the freezing point of the water, which means the ice on the ground can’t freeze that layer of water at 32 °F anymore. The water, however, can still melt …

WebTo help keep the water from freezing, people put salt on the roads. You may have wondered why they do this. Salt, when dissolved in water, causes the freezing point of water to become lower.
