Which of thse statements about saltwater is correct?
salt water freezes at a lower temperature
salt water freezes at a higher temperature
saltwater does not freeze at any temperature
salwater's freezing point depends on the temperature of the ocean floor.

Salt water freezes at a lower temperature. 

This is because when a non-volatile solute is dissolved in a volatile solution, the freezing point is lowered and the boiling point is increased.

Hope this helps :)
