Conclusion:

Salt lowers the freezing point of water. Normally, water freezes when the temperature reaches about 0�C. But when you mix salt with water, you actually lower this freezing point. Salty water will freeze but the temperature needs to be much colder than it would fornormal water. The more salt you add, the colder it must get before the water freezes.
