actually, you'll find that adding solute to water generally lowers its freezing point. That is why salt melts ice. If it is 0 degrees celsius, Ideal water freezes. When you add salt to it, the salt is ionized by the water molecules, dissolving it into solution. It takes a temperature of -5 degrees Celsius (this is just an example, not an actual value) for the water to break its association with the ions and freeze as a pure substance.

Well, I think that Salt doesn't melt ice (it's ice so it may not dissolve) but makes it melt at a lower point, I've herad about -20ºC I think...

Water is harder to freeze, i.e. freezes slower, if ice is added to it. That is why they put salt on the roads in icy weather. And the freezing point in the Fahrenheit system is 32 because Mr Fahrenheit used a mix of salt and water to calibrate the zero point of his system.

Adding salt to water lowers its freezing point. Water will not freeze faster if salt is added to it because the salt will allow the water to become super-cooled(lower than water's freezing temperature) which means the solution would have to be cooled farther before it would freeze.

it will make it freeze slower... just look at the ocean .. compared to a lake.

No.

yup, when salts solute in water they break apart as ions for example table salt, NaCl, becomes Na+(aq) Cl-(aq) water, which is already somewhat polarizes, reacts to the soluted ions by polarizing further, thus making the bonds between water molecules more powerful stronger bonds means more it takes more energy to keep them apart, means they'll solidify at a higher temperature

yes, salt water freezes slower because itt brings the freezing point of the water down to 21 degrees c.
