Technically, yes, but if you cook it, you'll end up with caramel because the sugar will start to brown before all the liquid evaporates.

You can let sugar-water evaporate over several days at room temperature and you'll be left with sugar crystals (or rock candy) in the bottom and sides of the jar. We did this in school when I was a kid. My brother's worked, but mine was discovered by ants and had to be discarded :( As an adult, I would have thought to cover it with cheese cloth or something to allow the moisture out but to keep insects from getting in.

Its like, when sugar solution is heated, the water molecules present in it evaporate. Sugar is basically carbon[C], right? so, a black spongy mass of carbon is left behind. Before this happens, as the water is lost, the solution get higher in sugar concentration and then the above process occurs.

Since about 500 AD, in India, sugar crystals have been obtained by solar evaporation.

Today the commercial production of sugar crystals is done under a vacuum to lower the boiling point.

Sugar crystals ARE obtained by evaporation. This is done under a slight vacuum in order to reduce the boiling point of the natural solution.

Otherwise, one relies on natural (solar) evaporation in a manner analogous to that used for salt.

Chinese manuscripts dating to about 8th century BC aver that the use of sugarcane originated in India. By 500 AD, the Indians were producing sugar crystals by solar evaporation in wide bowls called Khanda, and that word is the root of our word candy.

The sugar solution cannot be obtained by evaporating because when heat the water vapor will evaporate. When the vapor evaporates, the sugar crystals will crystallize.

What is obtained after distilling sugar solution?

sugar crystals


Can sugar be obtained by crystallisation?

Yes. As sugar can be charred by heat, we can't use evaporation. In crystallization, the mixture is heated until a concentrated mixture is obtained. Then the mixture is left to cool so that the excess solid particles in the mixture will precipitate out as crystals. eg. sugar from sugar solution


Will sugar crystals grow in soda?

Sugar crystals are suspended in the carbonated liquid. The only way that the crystals will accumulate is through evaporation and condensation. Open a can of soda and it will over a variable amount of time grow sugar crystals.

What method is used to separate sugar and water?

When water is mixed with sugar,the solution is called a sugar solution.We heat the sugar solution on a evaporation dish and the water will evaporate then leave it to cool and sugar crysatls (sugar) will be formed. But if you need the water to be obtained also ,you will need to use the process of "simple distillation".

Why does a sugar crystal grow faster in distilled?

There are not salts in the water to interfere with the growth of the crystals. Also, salts in the water will slow its evaporation.
