When the sun heat uup salt water, it absorps the water, but leaves the salt back, increasing the content of salt. In due course of time, all the water is absorbed and the salt is left back.

How do you prove that the sun can be used to separate salt from salt water?
If a saline solution (dissolved salt in water) is gently heated, the water will evaporate, leaving salt crystals behind. If the water vapour is captured and condensed, the result is drinking water. The heat used can be a hot plate on an oven, or the warmth from the Sun's rays. Either way, heat will cause the water to evaporate, leaving salt behind.
Which property can be used to separate a mixture of salt and pepper?
Salt is soluble in water, unlike pepper, so you can put the mixture in water and filter it using a coffee filter. The pepper will stay in the coffee filter and the salt can be separated from the water by leaving the solution in the sun.
How would you separate the sand and salt from a sample of sea water?
<p>You can separate the sand by filtration, but still the salt (mainly sodium chloride) is dissolved in the water. Then, you can separate the salt from water by distillation. The liquid you collect after water vapor is chilled is distilled water. You can use other methods to separate sand as sedimentation (usually slower than filtration) and salt as reverse osmosis.<p>
What does water in the sea turn into when it is heated by the sun?
When water in the ocean is heated by the sun it turns into water vapour and evaporates, however it leaves the salt behind as it is made of separate molecules.
How can you separate water from salt by using the sunlight?
leave it out for a day or two in a wide container. The sun should evaporate off the water.
How would you separate water from salt?
With a coffee filter, then you let it evaprate in the sun. If anymore questions contact me at: xoalysaxo98@aol.com
How might you separate a solution of salt water?
You can pour the solution into a tray and set in in sun light and leave it for several minutes.
Which water gets warmer first salt water or ice water?
The salt water gets warmer faster then the ice water, because salt water is in the sun and the salt water is heated by the sun.
How can you separate salt from sea water?
1 Pour water on the mixture of salt and sand. 2 filter the salt water out of the sand with a filter paper. 3 evaporate the water out of the salt water, leaving only the salt. the problem with this is when the salt desolves in the water the salt water also soaks into the sand so really when the sand dries out there is salt
What do the sun rays do to salt water?
The water evaporates under the sun leaving the salt.>
How do you clean salt water with the sun?
The water will evaporate and salt will be left ... so unless you want salt it is imposible to clean salt water with the sun
How can the sun be used to seperate salt from salt water?
The evaporation technique, simply leave the salt water to stand near a window during sunny weather, and over time the water will evaporate leaving just salt crystals behind.
