At the simplest, there are two steps;
1. Boil water
2. Collect the steam
In practice, there is a little more to it. It is difficult to collect water vapor, or steam; it is much easier to collect liquid water, so you will need a way to change the water vapor back into liquid water. You do that by condensing the steam back into water.
This turns out to be pretty easy to do; water vapor will condense into liquid on the outside of a cold glass if there is ANY water vapor in the air, as everybody who has held a cold drink on a hot day already knows.
If you are out camping, it is easy to make a "solar still" and get clean, fresh water from any kind of damp muck. Dig a pit in the ground about 18 inches deep where the sun can shine on it. Put any sort of damp material - green leaves, mud, dirty water, almost anything wet - and put it in the hole. Place a clean empty container such as a metal pot or bowl in the middle of the pit. Cover the pit with a plastic sheet; a tarp, a plastic trash bag, something to cover the entire pit. It doesn't have to be airtight or watertight. Place a small stone in the plastic sheet right over the pot.
The sun will shine into the pit and heat up the wet stuff in the pit. Some of the water will evaporate. The vapor will hit the plastic sheet, and condense, and run down to the bottom point in the sheet where the stone is, and fresh water will drip into the pot.
If the goal is to collect the salt, that's even easier; put a shallow pan of salt water in a the sun. Wait until tomorrow. The salt will remain, while the water will have evaporated.
Boiling off the water from a salt solution will separate the solid salt and water (which can be collected by a condenser).
One way to separate salt from water at home is through a process called evaporation. Simply heat the saltwater until the water evaporates, leaving behind the salt. Another option is to use a process called distillation, where the steam from boiling saltwater is collected and cooled to separate the salt from the water.
You can separate water from salt through the process of evaporation. By heating the water containing salt, the water will evaporate, leaving behind the salt. The evaporated water can then be collected by condensing it back into liquid form.
Use filtration to separate the sand from the water and salt. Then use evaporation to separate the salt from the water. Use distillation to evaporate the water, leaving the salt behind. Then use filtration to separate the remaining sand from the salt.
It all depends on the substance and its physical properties. For example, salt water can be separated by boiling the water and letting the salt remain.
Because the boiling point for salt ( NaCl ) is 1413 degrees Celsius, and the boiling point for water ( h2o) is 100 degrees Celsius, it is possible to boil salt water, and have the water evaporate, and the salt remain .
boiling
Salt will dissolve in water, and the more heat you add, the more salt you can dissolve, i.e. boiling the water. Sand however, is not water soluble, therefore, it will not dissolve. Let the water boil and dissolve the salt, then drain the water over a semi-permeable cloth so the sand is trapped and the water (and salt) drains through.
To separate the mixture of salt water and husk, you can use the process of filtration. Pour the mixture through a filter, which will allow the salt water to pass through while trapping the husk. The salt water can then be evaporated to recover the salt.
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)
Salt dissolves in water, sand does not. Mix water with the solids, pour off the water, and sand is left behind, Evaporate the water by boiling it, and the salt will be left.
Salt water, but the water will stop boiling because upon adding the salt it raised the boiling point of water.
