Pure fresh water freezes at 0° C. Average for sea water is about -2° C.
In a solution of more extreme salinity, the freezing point might be depressed to as low as -30° C.

Dose salt effect the freezing point of fresh water?
Of course not!!! If you added salt to fresh water, it wouldn't be fresh, anymore . . . gees.
Why does a test tube of fresh water freeze quickly in iced salt water?
salt lowers the freezing point of the water
Is salt water colder than fresh water?
The freezing point of salted water is lower than the freezing point of pure water; this is a phenomenon known as freezing point depression when a solute exist in the solution.
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.
Which water freezes faster salt water or fresh water and why?
Fresh water freezes at a higher temperature than salt water. This is because the presence of impurities in water lowers its freezing point.
What does salt have to do with the freezing point of water?
Adding salt to water the freezing point decrease.
Why does pond water freeze easier than salt water?
Saltwater has a much lower freezing point (the freezing point is the temperature where something freezes) than fresh water does. The more salt there is in water, the lower is the freezing point.
How come you cant freeze salt water?
Salt water has a much lower freezing point than fresh water. If freshwater is saturated with salt, the freezing point is minus 21.1 degrees celcius. The chemistry is complex, but in simple terms, saltwater becomes a different substance to fresh water, they have different chemical properties.
Why is the freezing point for ocean water lower than fresh water?
Because ocean water contains 3.5 % salt.
Which type of water freezes first fresh or salt water?
Fresh water freezes at a higher temperature than Salt water. So Fresh Water doesn't have to lose as much heat in a given amount of time in order to Freeze.
What is the freezing points of fresh water and salt water?
The freezing point of saltwater is lower than the freezing point of freshwater upto a specific ratio of salt & water. The freezing point goes below upto -11 C, but if you increase the salt content thereafter the freezing point will increase above 0 c. The sal and water mixture is usually termed as "Brine"
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.
