What temp. does salt water freeze at?

Answer 1

Yes, salt water freezes. The temperature at which this happens depends on
the salinity (amount of salt in the water). Ocean water is about 3.5% salt
(mostly sodium chloride, just like table salt). At this salinity, the
freezing temperature is about -2 degrees Celsius (about 28 degrees F), so
sea water can stay liquid for a little while after fresh water would freeze.

Answer 2

Salt Water Freezing Point

Answer 3

That depends almost entirely on the actual salinity of the water. Freezing point, more specifically freezing point depression, varies directly with the concentration (molality) of "salt" in the water. It also depends on the KIND of salt, as there is an ionic factor involved. Sea salt is actually a bunch of different salts, NaCl, MgSO4 and others. So it's more complicated than it seems.

Answer 4

What type of salt water, there are many kinds! You have to take into account the ionic atmospheres of each molecule and relate that in an activities equation. See water with different kind of salts will freeze at different temperatures.

Answer 5

Does Saltwater Freeze

Answer 6

Hi. It depends on the salt content. A mixture of pure water and salt in equal measure generates 0 C.

Answer 7

It depends on the concentration of the salt solution. A higher concentration of salt would result in a lower freezing temperature. In the specific case of seawater, the freezing point is about -1.8 °C, which would be 28.8 °F. The freezing point of pure water is 0 °C or 32 °F.

depends on the concentration , a standard solution freezes at 0F which is how 0 F was determined, sea water between -2 and -8 C

Answer 9

In the ocean, roughy 28 degrees F. As the other answers indicate, it can be pretty complicated but this is a good number for ordinary seawater.

Answer 10

not v sure. i gues it's -4'C but depends on other thing like soulbility and concentration of salt!
