When a mixture of sugar and water is frozen, does the sugar seperate from the water?

Answer 1

No it doesn't. Have you ever frozen a coke or had a slurpee? Notice that the sugar didn't separate. Mixing sugar into water will lower the freezing point, however, but it won't separate.

Answer 2

It depends on the concentration of the sugar. If it is very concentrated (like a syrup) and the mixture is slowly cooled (like in a fridge) the sugar will gradually crystallize out (like honey does).
If it is dilute, you will just have frozen sugar water. Although, again if cooled slowly, pure water will crystallize first, leaving you at the end with a relatively concentrated sugar solution amongst the ice, until it finally freezes.
That's why when you drink a partly frozen soda the stuff that's still liquid is so dang sweet.

Answer 3

At usual freezing temperatures like in your ref, NO.
The sugar molecules are dispersed and dissolved in water and the sugar solution although freezing at a lower temperature than pure water will just freeze as a whole.

At much lower temperature, it is the water that is separating from the sugar solution, as one of responders said, the remaining solution is much sweeter. The sugar did not separate. That solution has still sugar in it with less water. That water crystallized and separated as ice.

As another responder also said, depending on the concentration, it is possible for the sugar to separate and crystallize also, as in supersaturated and very concentrated solutions.

Answer 4

being a biology major, i'm going to say yes and no. when water freezes, it traps the sugar molecules inside itself (the structure of ice is rigid and perfect like a crystal and has many gaps in between it...this is why water expands when it freezes). they are never "together" to begin with. so yes they are separate but not in the sense that you have sugar on the bottom and water on top.

Answer 5

i'm not sure if the holes interior the coffee filters could be sufficiently small to seize Kool help powder. in case you're in midsection college or severe college, you ought to objective asking a chemistry instructor for some filter out paper and clarify what you're attempting to do. Chemistry labs usualy have filter out paper that has lots smaller holes than a coffee filter out does. Your buddy's theory could artwork too. If she is apprehensive approximately burning the Kool help, have her warmth all yet an extremely tiny layer of Kool help from the pot. Then have her supply up heating the pot, enable the pot sit down out over right here couple of days, and something of the water will evaporate with the help of itself. the two are the two sturdy techniques. sturdy good fortune alongside with your test. :)

Answer 6

i don't think so. water molecules will still encircle the sugar molecules

Answer 7

Yes because they have different freezing points.

Answer 8

i dont no but ill like to try that
