how do you get pure sand from a mixture of sand & sugar?

taste and spit, taste and spit, etc.

If this isnt a trick question, I would say that water would need to be involved here. If you mix the sand and sugar, and stir it up like you would do with koolaid, the sugar molecules will hide in the water molecules. Next, the water would have to evaporate, leaving you with just the sand, or maybe the sugar would still be there too if the water evaporates. Dont know if sugar works the same way as salt does or not… good question.

Pour very hot water over the mixture, the sugar will disolve and drain away leaving only the sand

sugar is crystallized glucose, sucrose, etc., sand is silicon (glass), and sedimentary debris. One dissolves in water, the other does not (hence sand being on the bottom of the ocean).

So, using a coffee filter, take a mixture of water, sand, and sugar, and run through the filter while also continually adding new, hot water into the mixture. Eventually, you will be left with just sand.

The sugar will dissolve in hot water and the sand will remain. Filter by Suction filtration in a Buncher flask and funnel and suck this dry, hey presto you have sand. Although not sure why you would want to do this 😛

Put it in a beaker of water, heat and stir. The sugar will dissolve and the sand will not. Filter out the sand and dry and voila you have pure sand!

Mix with water, dissolve the sugar and remove the sand

Add water, boil a while, let a string hang in the liquid, the sugar will “climb” the thread building crystals, leaving the sand behind.

Source(s): just know stuff

add water. it will dissolve the sugar.

then you have the sand alone on the bottom of the container

drain off water & sugar solution.

Put it all in a pan of hot water! the sugar will dissolve, the sand will remain.

pour water over the mixture. heat at a moderate temperature. this dissolvesa the sugar in the water. filter it using watmann 1 flutted filter paper and a normal filter into a clean, dry conical flask. leave for a week to throughly dry and there is your pure sand. prefably leave dry in a incubator.
