Does salt water freeze faster than cold?

Answer 1

For shear simplicity regular water freezes faster. Salt lowers the freezing point of water, to what degree depends on the chemical makeup of that particular kind of salt. For a more advanced answer we need to study the chemistry of both salt and water a bit more. Salt can contain any number of elements, (Ca-Calcium, Cl-Chloride, Na-Sodium, SO4-Sulfate... etc.) the more particles present of each element the lower the freezing point of water (H2O). When salt is added to water these elements join the chemical makeup of water and the salt basically gets in the way of the chemical interactions between H-Hydrogen and O-Oxygen. The amount of difference greatly varies depending on the amount of salt present and the chemical compound of the salt.

Answer 2

Salt doesn't make water freeze faster or slower.

Actually, it is not a question of faster or slower, but of the freezing point, or the temperature at which the water freezes. Salt added to water decreases the freezing point. So, on a day when the temperature reaches 32 degrees Fahrenheit, water with salt in it will simply not freeze (this is why fast or slow has nothing to do with it). The more salt, the lower the temperature must go in order for the water to freeze. This is true until the water reaches its saturation point (holds as much as salt as it can in solution), then adding more salt will not make a difference.

Answer 3

Salt water does not freeze faster than pure water, and it freezes at a lower temperature. Salt is a form of anti-freeze, which is why it is put on roads in the winter, to help melt the snow.

Answer 4

Salt does not make water freeze slower. However, if it was ice, the salt would melt the ice.
