Distillation is normally how it's done. You boil the water off, and that leaves the salt.
More often, the job is to separate the water from the salt. Although that used to be done by evaporating the water and then condensing it again using flash distillation, modern desalination is done by Reverse Osmosis. Let me explain.
Osmosis is a property of many membranes, like some plastics, skin and cell membranes. They allow smaller molecules, like water, to squeeze through small holes in the surface, but prevent larger molecules like salt from getting through. Osmosis happens when there is a stronger solution (like the salty fluids inside your skin) on one side of the membrane and a weaker solution (like bathwater) on the outside. The fluid seeps through, trying to dilute the stronger solution, and you get wrinkly skin.
With reverse osmosis, we push water the other way, forcing it with pumps to move from the stronger salty seawater to the pure water we collect. The now stronger salt water (we call brine) is dumped back into the sea.

As the steam cools it will return to it's water form and be salt free. The pan you boiled it in will now have all the salt residue in it.

∙ 13y agoNo you cannot separate sand and water with a funnel. You must use the process of evaporation where you heat the mixture of sand and water. When heated the water will begin to evaporate leaving you with the sand.

How do you separate salt and oil?
HOW TO SEPARATE SALT FROM OIL .First of all to separate salt from oil you need to pour some water, salt, and oil into a beaker in that order. .After you have put those materials in the beaker, you should see the salt dissolving, then you should be left with oil and water. .Next to separate the oil from the water you could either, leave the solution for a while and the oil eventually should rise to the top and float above the water, or you could use a funnel with a stopcock at the bottom which will allow you to drain the water out underneath the oil. GOOD LUCK! :)
Separating sand and salt?
Add water to the mixture of sand and salt, stir the mixture vigorously, pour off the water into another container, boil water off or let it evaporate. Sand does not disovle and once the you pour off the water and the water is gone all you will have left is the salt.
Could you use condensation to separate something?
Yes. You can use condesation to separate water from salt water leaving salt contents only
Could evaporation be used to separate salt and water?
Yes it can be used to evaporate the water which will leave the salt
Describe a pocedure that could be used to separate a mixture consisting of sand and salt?
Place the mixture in water and separate the sand from the water if you want the salt. alow the water to evaporate, and you have salt and sand separated.
What pieces of equipement should be used to separate salt water?
funnel
Which of these could you use to separate a mixture of sand and salt?
Salt is soluble in water where as sand is not. Using a fine paper filter in a funnel the salt can be removed from the sand by rinsing the mixture with water and then the salt can be retreived by evaporating the water. Hope I'm not doing your homework for you
What equipment used to separate salt water of the mixture magnet balance funnel or hot plate?
I believe it is a hotplate

Which of the following pieces of equipment should be used to separate a mixture of salt water magnet B balance C funnel D hot plate?
Look at each of the options and really think about what each one would mean and need. To separate a mixture of salt waterA magnet - There is no metallic substanceB balance - There is nothing to weighC funnel - A funnel can direct water away, but the salt is IN the water.D hot plate - If you heat a salt-water mixture, the water will evaporate, and the salt will crystallize and be left behind. So I would choose D.
How you could use water to separate salt?
Evaporate water, then the salt would be separated.
How can separate water and salt without lossing of water?
Get a filter funnel and filter paper and pour in solution . water will run through and salt left behind
How could separate the salt from the water in the solution?
Boil the water off. It leaves the salt behind.
Separating sand and salt?
