can you freeze sea water ?

Answer 1

Yes, every thing can and will freeze...

Answer 2

Most icebergs are formed on land from fresh water (actually snow that gets compressed into ice in glaciers.)

The pack ice in the Arctic Ocean does result from freezing sea water. In the process a lot of the salt and other minerals are expelled so the ice has a much lower salt content that the original water.

You could do a simple experiment. Dissolve some table salt in water. Pour you salt water into a plastic cup (don't use a glass; the expansion of the ice might break it) or tumbler and place it in a freezer. Let it sit overnight to get as frozen as possible. Carefully extract the ice from the tumbler by warming the outside of the tumbler. Slide the ice out over a bowl to catch any liquid. You might try tasting the ice at the top and the bottom. You might find undissolved salt in the bottom of the tumbler or at least water that is much saltier than you originally mixed.

Answer 3

Of course ... everything can be frozen if it gets cold enough. It's just that the salt lowers the freezing point of the water. In the case of the ocean salinity, sea water will freeze at roughly minus 1.91 degrees C or 28.5 degrees F

At zero degrees on the Kelvin scale (= -273.15 C or -459.67 F) all matter is essentially frozen solid.

Answer 4

Yes, G man says it how it is.

Icebergs and polar caps are mostly fresh water.

The act of freezing SALT water actually pushes out a great deal of the salt and therefore the salt water ice is less salty than the water that was frozen.

Answer 5

Yes. But it takes a lower temperatrue than the normal 32 degrees fahrenheit (0 degrees celsius) to do so. The freezing temperature of seawater is munis 1.8 degrees celsius or about 28.8 degrees fahrenheit. This is due to the salinity, or salt contend of the water which is approximately 3.5 percent or 35 greams per every 1000 litres of water.

Answer 6

Freezing point depression... anyone else make ice cream in HS chemistry?? Change in temp = - k*i*m, and where k is a constant depending on the identity of the solvent, not whatever is dissolving in it (solute), i is the number of ions created when dissolved (NaCl in water, i = 2) and m is the concentration of the solute. Obviously, sea water has other stuff in it than just NaCl

Answer 7

Icebergs are actually frozen fresh water. Salt/sea water does not freeze due to the salt content in the water

Answer 8

yes I'm pretty sure anything can be frozen if you can get it cold enough. the salt in the water just makes the "waters" freezing temperature level lower. i read someones answer saying that ice burges is salt water. i can't remember fully but i think someone told me that it was fresh water.

Answer 9

no... sea water cannot be frozen it's chemically impossible due to the sodium...

as for the other smartalec answers:
Iceburgs are frozen fresh-water..... which makes up 98% of the fresh water in the world.... and they are floating sea water...
and antartica has solid ground with fresh-water ice

Answer 10

yes. it freezes at a lower temperature than less salty water.
