It causes a freezing point depression. The more salt you add to water the lower the temperature has to fall to cause it to freeze until you reach the cryohydric point. The cryohydric point for water with NaCl is about 29% NaCl at -22 C. Water molecules have to interact with each other to form ice crystals, when they interact with a salt molecule nothing happens. So the more salt that dissolves into the water the harder it is for water molecules interact with each other to form ice crystals.

∙ 14y agoSalt is capable of lowering the boiling point of water to make it boil faster as well as lower the freezing point of water by disrupting the equilibrium and allowing molecules to keep moving. Traditionally when things freeze the movement of molecules slows down, salt prevents that from happening! See the following website for more about the mechanism....

How much percent of water is salt water?
Estimates are that 97% of the water on earth is salt water or brackish water, the majority of it being in the oceans, seas, and bays. About 2% of the freshwater is frozen in glaciers. And less than 1% of the freshwater is in lakes, rivers, streams, and potable groundwater. See Links.
Which melts faster salt water or non salty water?
Salt water freezes at a lower temperature, which is why salt is used to melt road ice. In an environment where the temperature is slowly getting warmer as to melt the ice, frozen salt water will melt quicker than ice.
Does salt separate when frozen?
no
Will salt water remain frozen longer than fresh water?
Fresh water freezes at 32°f (0°c) at sea level. Sea water freezes at 28.4°f (-2°c) at sea level. Salt water depends on the concentration of salt. At maximum saturation salt water (23.3% by weight) freezes at -5.98°f (-21.1°c).
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.
Can drinking salt water prevent you from being pregnant?
No.
Which is colder frozen water or frozen salt water at melting points?
The freezing point of salted water is lower compared with the freezing point of pure water. So when melting frozen salt water is colder.
Frozen salt water melt faster then frozen fresh water?
Salt lowers the melting or freezing point of water. The effect is termed 'freezing point depression'. Therefore frozen salt water melts faster and remain melted for long.
If sea water is frozen will the salt go away?
no, the salt wont go away it will just be inside the frozen water i don't think salt freezes though.
If salt water freezes does the salt freeze to?
If the salt is still in the water it will freeze inside the water so its technically frozen
Can you separate water from salt when frozen?
No, not from the frozen state. 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.
Is frozen salt water heavier than frozen water?
The density of saline water is greater than the density of pure water.
Can salt water be disalted by freezing?
No, it just turns into frozen salt water. What you should do is evaporate the water and then you'll be left with salt crystals.
Will fresh water be completely frozen before salt water?
yes
Does Salt separate from sea water when frozen?
yes
Do salt water pools require anode rods to prevent corrosion of metal pool parts?
Ive never heard of them being used before in salt water pools.
What does table salt do to water when frozen?
salt lowers the freezing point of water. so the temperature that salt water freezes at is much lower than just water.
