It depends on what you would like to do with the two resulting products.
This is a simple problem to solve because of a fundamental reality of the two items you are trying to separate...one dissolves in water...and one does not.
"Pure" sand is primarily composed of Silicon Dioxide (the primary component of typical window glass) with some other mineral elements...none of which appreciably dissolve in water...
Salt, on the other hand, readily dissolves in water (to a greater degree with increasing water temperature).
Thus, to "separate" sand from salt...the easiest way is simply to put the sand in some kind of filter (coffee filter?) and run hot water over it while mixing it around (to make sure you have "extracted" all of the embedded salt).
If you simply want to "clean" the sand, this would work fine and you could just let the saltwater run into the drain.
If, however, you are trying to "extract" the salt and retain it for some purpose, you would have to catch the hot saltwater runoff from the process in some type of vessel and then simply either allow the water to evaporate or boil it off and the salt crystals would remain in the vessel.
sand+salt=sand salt
Because it is made up of small, solid particles.
Salt and sand is a mixture.
You can dissolve the sand and salt into the water. when this happens the salt will be dissolved and the sand will stay at the bottom. then get some filter paper and pour the mixture through it. the dissolved salt and water will go through leaving the sand. there you have the sand aside. to get the salt aside just boil the water until it evaporates completely and you will be left will your salt. then you have your sand and salt separated. by sifting it
You toss the sand and salt in a filter that will not allow the sand through, Then rinse the sand with clean water until all of the salt has been dissolved and removed from the sand, Then evaporate the water and you will have the salt separated from the sand.
If you dissolve the salt and the sand in water the sand will stay beind and the salt would dissappear. But if you want the salt back you can evaporate it off, by boiling the water. (with the dissolved salt in it)
Undissolved salt is salt that has not been dissolved in water, e.g rock salt or cooking salt.
To separate a mixture of salt and sand, you can use the method of dissolving the salt in water and then filtering the sand out. If the mixture consists of iron filings instead of salt, you can use a magnet to attract and separate the iron filings from the sand. This method works since iron is magnetic while sand is not.
If water is present salt is dissolved.
To separate sand from salt and pebbles, use a sieve to filter out the larger pebbles first, then add water to dissolve the salt and separate it from the sand through filtration. To separate salt from sand and pebbles, dissolve the salt in water and then evaporate the water to obtain the salt crystals, leaving the sand and pebbles behind. To separate pebbles from sand and salt, use a sieve or filtration to separate the larger pebbles from the sand and salt mixture.
You get a mixture of salt and sand. Nothing more happens.
Add water and stirr: salt is soluble, sand not. Filter the solution. On the filter re- main sand, in the solution salt. After repetitive evaporations you can obtain salt as crystals.
