How can you separate salt and sugar?

Answer 1

Organic Solvents

Benzene and other solvents will dissolve sugar, but not salt. Salt is slightly soluble in ethanol, but this method can be used for experiments. Add the mixture to ethanol and strain out the salt with filter paper. Evaporating the ethanol will leave the sugar behind.

Water Solution First in a large glass of cold water and mix the "Salt+Sugar" you have there.

Then wait until some solid particles form on the bottom of the glass.

Carefully take the water out of the glass.

The solid particles are SUGAR

Then the water is SALT+WATER

Take the "Salt+Water" and boil it until there is no more water.

Then you will end with just SALT (hot salt...)

In theory, if a water solution is cooled, sugar crystals should precipitate before the salt, but this is difficult to control experimentally.

Answer 2

Sugar is soluble (dissolves) in alcohol, where as salt is insoluble (does not dissolve) in alcohol. If you mix sugar and salt into alcohol then filter the solution, only salt will remain. After this, you can evaporate the alcohol out of the sugar. Voila!

Answer 3

Sugar will not dissolve. If you have a solution of sugar and salt, and you were to evaporate the water, both sugar and salt would be left. In order to remove either the sugar or the salt, you would have to use a chemical reaction that would cause either the salt or the sugar to undergo a chemical change.

Answer 4

Put the mixture in alcohol. The sugar will dissolve, but the salt won't. Then, you can separate them.

Answer 5

No because sugar is organic and will dissolve in organic solvents such as achol salt will not.

Answer 6

You cant separate them, because if you try to add water they will both dissolve and if you try to evaporate the water you will be left with both the salt and sugar again.

Answer 7

You can separate dry salt and sugar by adding alcohol.

Answer 8

Yes by electrolysis
