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 effect does salt have on the freezing pont of water?
It lowers the freezing point.
Does salt water freeze at a higher or lower freezing point than freshwater?
Salt water freezes at a lower temperature because the high salt content in the water lowers the freezing point but not by a lot.
Why does salt can melt a ice cube faster than pepper?
Because salt dissolves into water. The resulting mix (salty water) has a lower freezing point.Pepper does not dissolve into water.
Why The freezing point of salty water is less than that of pure water?
Depression in freezing point is a colligative property of solutions. When salt(solute) is added to the water(solvent), the vapor pressure of the water decreases. As a result, the freezing point of the water is lowered and hence salt water takes longer to freeze than pure water.
What are the effect of impurities on the freezing point of water?
An impurity, such as salt lowers the freezing point of water by interfering with the lattice structure water makes with hydrogen bonding at it's freezing point.
What does salt have to do with the freezing point of water?
Adding salt to water the freezing point decrease.
How to desalt water?
distill the water
How does salt keep water from freezing on your roadways?
Salt lowers the freezing temperature of water, which means that it has to be colder for the water to freeze.
What is the best way to desalt saltwater?
The only way i know to truly remove salt from water is to boil it and collect the evaporation.
How does salt affect the melting and freezing point of water?
Salt decreases the freezing point of water and increases the boiling point of water.
The process of what squeezes the salt out of salt water?
Freezing
How do you desalt salt water?
evaporation (heating up water so all the water is separated from the salt) filtration (this is the easiest way of collecting the water, but is the least accurate) dessication (would not be used if trying to obtain water, and would not be used with water and salt) hope it helps :)
Why does salt effect the freezing point of water?
Salt mixes with the water raising it's freezing temperature above normal.
What is the freezing point of salt?
Salt, being a crystalized mineral with no water content has no freezing point.
How do you desalt water?
to desalt water you will need a bowl , water ,and salt.you will first put the water in the bowl.then you will put the salt in.after that you get a spoon and stir the water and salt.then put it in the freezer and wait 3 hours.once the 3 hours are over you will not see the salt.if u do it would be dottoed all around.if u see the salt you did not follow the steps.i hope this was usefull.see ya people of vegas.
Why does the freezing point affect the freezing of salt water?
It does not, but salt affects the freezing point. All solids are frozen. Each has a different freezing point. Ice is just the freezing point of water. But your computer keys are frozen too. Different substances freeze differently. But for your purposes, compare water to salt water. The salt in the water causes there to be more things in the water that disrupt the tight hydrogen bonds.Since freezing is tighter H-bonds, salt lowers the freezing temperature because it is harder to freeze it now since there is salt in it.
Can you seperate salt from water by freezing?
no
