how can we separate mixture of salt and sugar in an easy way?

Answer 1

sugar is organic,(contains carbon) and is soluable in organic solvents like alcohol. Salt is insoluable in alcohol.

Add alcohol to the mixture, filter out the salt, then evaporate the alcohol and the sugar will be left

Answer 2

A better yield can be obtained with benzene and water. The partition coefficient is greater. Or you could use fractional crystallisation.

Answer 3

Lancenigo di Villorba (television), Italy you haven't any longer explicate your question. I understood an excellent mix of kitchen's salt and sucrose. whether that's perfect, I actual have yet another concept for you. I no longer believe PRECEEDING solutions. you could't danger to proceeding in "dry warming" strategies, given which you're able to desire to "caramelize" the sucrose ("empireumatism"). In nutrition's industry, sucrose is rescued by making use of its aqueous suggestions by making use of including lime and long-term final jointly. In result, lime coach a interplay with sucrose, so the latter form a white precipitate at backside's vessel. Acidic scientific care of those bodies re-form sucrose suggestions which ends up "different-loose". consequently, lime permit an alkaline scientific care that separate sucrose. on the different hand, the extra desirable fraction (e.g. halide salts like NaCl, MgCl2) of kitchen's salt maintains to be in aqueous answer. different fraction of kitchen's salts coach a distinctive behaviour, see carbonates and sulphates. The latters would react with lime and would precipitate CaCO3 and CaSO4, as few soluble calcium's compounds. in case you bring about heat-bath circumstances, you could evade carbonates and sulphate's pollutants of precipitate. After filtration, you shop won white good. The latter is put in a sparkling vessel (e.g. one Drexel's equipment) the place is submerged by making use of a mix of deionized water and ethanol (e.g. absolute ethylic alcohol). This hydro-alcoholic mixture permit you low solubility of calcium's compounds constituing white precipitate and satifacting solubility of air's gasoline. between air's gasoline there is carbon dioxide. You closed tightly the Drexel and you expirate your breath in apposite pipe. Expirated gasoline-flow form bubbles in alcoholic mixture, so carbon dioxide react with calcium's compounds. recently, you're able to receive sucrose's answer in alcoholic media, for that reason sucrose is finally separated by making use of calcium's compounds. Sucrose's answer is concentrated by making use of commencing the Drexel ; this answer coach extreme vapour's rigidity, for that reason it dry itself. i wish this facilitates you.

Answer 4

The above solution (alcohol) with not work with regular alcohol (ethanol) because ethanol will dissolve NaCl. use propanol or butanol

Answer 5

However, alcohol would be safer for a student to use, since benzene is carcinogenic.

Answer 6

My answer similar to the above-a smart chemistry teacher!

Answer 7

simply boil the water.

Answer 8

indeed..davidosterberg1 is correct....
