What Is Freezing Point Depression?
Freezing point depression is the lowering of the freezing point when a substance is added to a solvent. Using salt to melt ice on roads is an example of this.
How is it calculated?
How Is It Calculated?
ΔTf = i × Kf × molality
Kf: freezing constant.
- Enter the molality, the constant and the factor.
Frequently Asked Questions
Why does salt melt ice?
Because the dissolved substance lowers the freezing point, the ice melts at a lower temperature.
