Salt candissolve ice, so the salt in sea water act like a antifreeze.
Sea Water would probably start freezing at - 15C

Put both in the freezer and use a timer. It must be in a freezer, because if you have ever heard of super-cooled water, a lack of vibrations causes water to remain liquid below the normal freezing point (0 degrees Celsius), that is if it is not disturbed at all.
0 degrees Celsius, or 32 degrees Fahrenheit
The freezing rate in order of fastest to slowest would be: tap water, bottled water and then salt water. Although it's a toss up between bottled water and tap water. The more sodium content of a solution, the slower the rate of freezing. In fact, a supersaterated sodium solution has to have a temperature of -21 degrees Celsius in order to freeze. Any temperature above that, will cause the salt to melt the ice. That is why they use use salt on icy roadways in the winter. If the ambient temperature is below -21 degrees celsius however, ice on the roads won't help. So salt water would be the last to freeze. Why did I say tap water before bottled water? Bottled water usually, but not always, comes from natural springs. Although some people prefer this water over tap water, spring water can contain minerals, such as sodium (salt), calcium, which can slow the rate of freezing, unless the temperature is low enough. Tap water is wastewater that has been treated with chemicals (such as chlorine) and and filtered prior to it being sent to your home. The addition of these chemicals shouldn't slow down the rate of freeze and that's why I said it's a toss up between bottled and tap water. The difference in chemical make-up shouldn't interfere with the freeze rate, especially in a home freezer. Note that water at room temperature tends to freeze slighlty faster then cold water in a home freezer.
Plain water because the salt in the other water lowers the freezing point. All molecules must line up in order to freeze, therefore if adding salt, the Na and CL must line up with the water molecules in order to freeze. With plain water, the molecules line up faster and thus freeze faster.
Below zero. How much below depends on the salt concentration.
Yes, it can.

Adding salt to water and ice lowers the freezing point of the mixture, causing the ice to melt. This occurs because the salt disrupts the hydrogen bonds between water molecules, preventing them from forming a solid structure. As a result, the saltwater mixture remains in a liquid state at a temperature lower than 0°C.
No. But ice and water with table salt dissolved in it, can.The salt lowers the freezing temperature of the water, so that it can remainliquid even when it's below 32° Fahrenheit (0° Celsius). In that condition,it can be used to cool the can in which the ice cream ingredients are mixed, andcan freeze it faster than solid normal ice could.

Water will freeze faster than salt water.
The salt is a substance and it a ingredient that will not freeze.
If the salt is still in the water it will freeze inside the water so its technically frozen
Saltwater freezes into ice at a temperature below 0 degrees Celsius or 32 degrees Fahrenheit. The exact freezing point can vary depending on the salinity or concentration of salt in the water. Generally, the presence of salt lowers the freezing point of water compared to pure water.
if you add salt to water, it will freeze at a lower temperature.. i do not think it is possible at a temperature below zero degrees.
Adding salt to water increases its density and lowers its freezing point. ---------------------- I've just completed a repeated experiment on the effects of salt and the freezing point of water. A saturated salt solution will not freeze at -15 degrees Celsius (my freezer temperature). At exactly -21.1 degrees Celsius the salt begins to crystallize out of the solution, along with the ice, until the solution completely freezes.
