Stop sugar from dissolving in water?

Question

Is there any way to change water activity to prevent sugar (sucrose) from dissolving in it?

Answer 1

Freeze it.

Answer 2

Sure,

Remember what happens when you dissolve sugar in water? You create a solution. So what's a solution? The sugar molecules are in the spaces of the water molecules. So all you have to do is fill those spaces with something else like salt or more sugar.

Answer 3

You could, once it is already dissolved, boil the water so that it goes up as steam and at the bottom of the container the sugar would be left behind since it has a much higher boiling point.

Answer 4

Sugar is water soluable. It's in the nature of the sugar, not the water.

You have two good answers offered:

Freeze it so that no more chemical reactions take place.

Or put enough suger so that the water becomes saturated so that it can absorb no more. After that point, any additional sugar will simply fall to the bottom, undissolved.

Answer 5

Solubility decreases with a decrease in temperature.Therefore the lower the water temp,the lower the amount of sugar dissolved.
Secondly,you could saturate the water.

Answer 6

Saturate it first, then adding more, it would not allow to dissolve any more in it. Try salt water, or very cold water.

Answer 7

No. Unless you freeze it immediatly after adding sugar.

Answer 8

Adding a lot of it to make it substrated

Answer 9

For what practical reason would you want to do that?

Answer 10

Not that I know of.
