Freezing Point Depression Calculator: Calculating Freezing point depression became difficult for you? Don't worry we came up with an exciting tool that provides the result in seconds. To determine the freezing point depression give the FPD constant and the molality. Scroll down to know more about the definition of FPD, how to calculate manually, and many more.

## What is Freezing Point Depression

Freezing point depression is the temperature at which the solid solvent and liquid solvent are in balance so that the vapor pressures get equal. When a non-volatile solute is added to the volatile liquid solvent then the solution of vapor pressure is lower than that of the pure solvent.

Look into the formula that we can use to calculate the freezing point depression.

Freezing point depression = Molal freezing point constant*Molality

ΔTf = Kf*m

### How do you Calculate the Freezing Point of Depression?

For calculating the freezing point depression you can follow the steps that are given below.

• The main thing you need to do is take the values that were given in the problem.
• Determine the values of freezing point constant and molality.
• Then, apply the formula, i.e. ΔTf = Kf*m.
• Substitute the values and simplify them.
• Finally, you will get a freezing point depression value.

Example:

Question: Find the freezing point depression if the freezing point constant is 120 KKPm and molality is 0.023?

Solution:

Given values are, Kf = 120KKPm

m = 0.023

Apply the formula,

ΔTf = Kf*m

ΔTf = 120 * 0.023

ΔTf = -270.39 C

Therefore, the value of the freezing point constant is -270.39 Celsius.
