Essential question: What effect does salt have on the freezing point of water?
Learning outcomes. Students will investigate how salt lowers the freezing point of
Quick Answer. Salt lowers the freezing point of water. The freezing point of water
is the temperature at which water transitions from liquid to solid phase.
The freezing point of a liquid is lowered when there is an additive, such as salt or
sugar. The higher the salt or sugar content in a liquid, the lower its freezing ...
Effectively, the salt molecules stop some of the water molecules from touching the
part of the water that is becoming solid. At 32 degrees Fahrenheit, water ...
