is it possible to freeze anti freeze or salt?

Question

Please give me a scientific answer no answers less then 3 sentences please

Answer 1

When you freeze a pure liquid, once it reaches it's freezing point, the temperature will stay essentially constant untill all the liquid has solidified. But it is different when you try to freeze water containing something that reduces it's freezing point. Here's what happens. As you get it colder and colder it goes below the normal freezing point, eventually some of the water will start to crystallize (freeze). When this water freezes, it drives the dissolved material out of solution as it solidifies, so the frozen portion will be nearly pure water. Thus, the dissolved material is now contained in a smaller amount of liquid water (this is the same as if the solution became more concentrated). So the required temperature to continue freezing more water is now even lower. If cooling is continued, more water will crystallize but, the more water frozen out of the solution, the harder it becomes to continue to freeze out more water. Usually you won't get solid ice from solutions like this, generally, you'll get slush and residual, very concentrated, solution. If you ever had a can of soda freeze and explode all over, you saw a perfect example of this phenomenon, the water partly froze out driving the syrup and carbon dioxide into the remaining liquid, water can only hold just so much CO2, so the presure in the can starts rising untill it bursts, spraying slush and syrup everywhere.

Answer 2

Antifreeze will freeze. The amazing characteristic is that when water is added the freezing point actually gets lower! The lowest point being when you have about a 60% mixture of antifreeze to a 40% mixture of water. I think pure antifreeze will freeze at around 8 degrees F.

Answer 3

Yes, you can freeze anti-freeze. Just about everything will freeze close to absolute zero, expect Helium.

Common salt is already a solid at normal temperatures, so it is frozen.

Answer 4

Yes but you need to get it really really cold.
