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.

Can water be used to separate salt from sugar why or why not?

A mixture of salt and sugar can be separated by using an organic solvent to dissolve the sugar. When the sugar is dissolved, it can be separated by filtering the salt from the liquid sugar,then recrystallise both solutions to from back their original crystals.

What can I do to separate sugar and salt?

Pour the mixture in alcohol. The sugar will dissolve and the salt can be separated, and then, pour water on the alcohol/sugar solution. Wait for the water/alcohol to evaporate, then the sugar will be left.
