You can separate water from alcohol by fractional distillation. By heating the mixture to the right temperature, the alcohol will evaporate and leave the water behind. However, alcohols and water are quite difficult to separate completely, and the separation will not be 100% by this method.
Mixture is heated slightly to evaporate alcohol which has lower boiling point . Vapors are Condensed. Process is repeated several times also called fractional distillation to separate both .
The separation is possible by distillation.
Distillation.

Salt does not desolve in pure grain alcohol. Put the mixture in the solution, then filter through filter paper or a coffee filter. then evaporate the alcohol and your left with salt in the filter and sugar in the other end.
Organic SolventsBenzene 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 SUGARThen the water is SALT+WATERTake 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.
Sand and water can be separated by Filtration.
Boiling off the water from a salt solution will separate the solid salt and water (which can be collected by a condenser).

If you need to make an intoxicating drink you can distill a mixture of alcohol and water to make spirits.
fractional distillation
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.
water and alcohol have different boiling point; you heat them untill the boiling point of the alcohol( the boiling point of alcohol is lower than water) so that you can collect the evaporated alcohol and left behind the water.
alcohol and water have different boiling point. i.e bp of alcohol is78C andwater is100C
The pepper can be filtered out with filter paper. The alcohol is trickier, and must be distilled out (see related questions).
Ethanol and water are miscible. Think of alcoholic drinks, the alcohol and water do not form separate layers.
Previous answer: "You can use distillation to separate alcohol and water due to their different boiling points."Not quite. You can partially separate alcohol (ethanol) and water due to their different boiling points. Water and ethanol form what is called an azeotrope, meaning that at a certain concentration of ethanol (somewhere around 94-96% I think, not sure) you can not separate the water and ethanol to any greater extent through distillation. It is still possible to get 100% ethanol, but this has to be acheived either through exhaustively exact synthesis or using a water sequestration or drying agent on a water ethanol mixture and re-purifying the ethanol by whatever process is relevant.to separate this liquid -liquid mixture we must use-fractional distillationbecause alcohol for eg. methyl alcohol boils @ 64.7 C& water @ 100 C
Alcohol has a lower boiling point than water so you can boil it off. _________________ Alcohol burns, water does not, so you could set the mixture on fire. Of course, you would lose the alcohol that way....and actually,....you would eventually lose the water too, because it might evaporate due to the heat!
Alcohol is miscible in water, so they can't be separated by straining or settling. Your only choice is fractional distillation.
