Does salt water have a higher or lower freezing point?

    Salt water has a lower freezing point than water without as high of a salt concentration. It is something that is referred to as a colligative property, meaning that the amount of substance, not what it is, dissolved in the water determines the freezing point depression.

    Salt water freezes at a lower temperature than freshwater. That’s why at the north pole, you can have frozen freshwater icebergs floating above the liquid ocean water below.

    Because salt water is more dense than freshwater, due to the salinity, it takes longer to freeze, and freezes at a lower temperature. Ocean water freezes at around -1.8 degrees Celsius, where as fresh water freezes at 0 degrees Celsius.
