does salt water freeze?

Yes. Sea water freezes at about minus 4 Celsius. I worked in the Dry Valleys in Antarctica once. The temperature was below zero, it's got the lowest humidity of any place on Earth; about 2%, and because it's environmentally fragile, all garbage and waste has to be choppered out. We used to do wee wee into an open 44 gallon drum. The widdle became more and more concentrated as the water evaporated and it didn't freeze; when the drum was nearly full it consisted of half-frozen slush, and the drum was choppered out and emptied into the Ross Sea.

Will Salt Water FreezeSource(s): https://shrinks.im/a9HcZ

Yes, It does. If you start with a glass of sea water, it will start to freeze at a lower temperature than fresh water (around -4 C, but variable depending on the salinity you start with).
Important, the salinity of the ice formed it is almost pure water (it is not salty). Some salty water may be trapped on the ice though, but the ice itself is fresh water. If you keep lowering the temperature, more ice will form and the remaining salty water gets even saltier. This process will continues until an eutectic is reached and then you will have a fast crystallization of ice, a mineral called hydrohalite (I guess you can consider this freezed salt water) and/or salt (depending on your starting composition). This eutectic is about -21 C, but depends on other components, like Mg, Ca that are also abundant in the composition of sea water.

Yes, salt water can freeze. It just freezes at a lower temperature than non-salty water. The amount by which the freezing point is lowered increases with increasing salt content (as in the more salty the colder the water needs to be to freeze).

Salt water can in fact freeze, but it has to be a lot colder than normally needed for normal water to freeze.

yes salt water does freeze however due ot teh salt content it does not freeze at 0 degrees celsius but at a much lower temperature.

Yes, actually. Salt water does not freeze at 32F though. It can freeze at any different temperature. Why? It depends on how much salt there is in the water. The more salt there is in the water the less the temperature iti is going to freeze at.

If by 'salt water' you mean the oceans and seas then yes, that water does freeze. The oceans around the Arctic and Antarctic freeze.
