Yes, seawater can be desalinated by freezing. The ice crystals that are formed are pure water and the salt crystals get trapped between them. The salt and ice crystals then need to be separated.
This is not particularly efficient and other ways are more commonly used such as distillation and reverse osmosis.

∙ 12y agoFirst off you have to fill two cups up with water and fill them with sea salt, stir until the solution has merged into one.
After doing this set one of the glasses into the ffreezer, let the other way stay out in the open but make sure to seal off the top of the cup.
Check regularly on your cup of salt water in the freezer until it is partially frozen. (Don't make the mistake of compeltly freezing or not freezing it enough)
Finally take a bowl out and empty the glass full of ice and slush into a cheesecloth (a clothe with holes in it) Take the ice out of the cheese cloth, you can either wait until this melts or put it on the burner until it melts.
Finalyl taste both the solution you didn;t freeze and the one you did, can you atste a difference?

How do you desalt salt water by freezing?
Because water wants to freeze in it's pure form, you can spray water into cold air. As the water begins to freeze in the air, the salt is pushed out. By the time it lands, the frozen water is pure and since some of the water contains all the salt, it drains off. The ice that is left is de-salted.
What physical standards are Fahrenheit and Celsius temperature scales linked to?
The boiling and freezing points of pure water and sea level.
Does sugar water boil at 100 degrees Celsius?
(At sea level) no. Sugar raises the boiling point as well as lowering the freezing point.
What type of change is freezing water?
Freezing water is an example of a physical change because the material contents of the water has not changed.
Freezing point of sea water?
Water freezes at zero degrees Celsius or 32 degrees Fahrenheit at sea level.
How to desalt water?
distill the water
Which body of sea water have the lowest freezing temperature?
dead sea
Why is the freezing point of salt water important for animals living in the sea?
There are organisms living in the sea. When it is winter, the sea water will not freeze easily thanks to the salt in the sea water, which lowers the original freezing point, and therefore saving the animal's lives.
Why does sea water freezes faster than fresh water?
sea water doesnt freeze faster than fresh water, fresh water freezes faster than sea water as it has a lower freezing point than sea water has as sea water contains salt which makes the boiling/freezing points increase therefore making the sea water freeze at a lower temperature.
What is the freezing point of sea water and pure water?
the sea water contains more salt. the pure water do not contain salt. the density of sea water is more than density of pure water. as there is more salt in sea water it is corrosive against the metals like aluminium. the pure water is not corrosive in nature. sea water is harmful for drinking. pure water is good for drinking.
Why sea water freezes at a lower temperature than fresh water?
The salt present in sea water lowers its freezing point.
Why does sea water freezes at a lower temperature than fresh water?
The salt present in sea water lowers its freezing point.
Why in polar regions some of the water is frozen to snow while sea is left unfrozen?
The sea is salt water which has a lower freezing point than fresh water in the snow. Additionally the sea is continually moving (waves) which will need a lower temperature to cause freezing
What does salt do to the sea?
Salted water is denser than pure water; the freezing point is lower.
How do you desalt salt water by freezing?
Because water wants to freeze in it's pure form, you can spray water into cold air. As the water begins to freeze in the air, the salt is pushed out. By the time it lands, the frozen water is pure and since some of the water contains all the salt, it drains off. The ice that is left is de-salted.
Why due to salt sea water freezes less often?
Because the sea water contain salt the freezing point of this solution is lower.
What is the freezing point of water at sea level. (Celsius)?
Water freezes at zero degrees Celsius or 32 degrees Fahrenheit at sea level.
