The image above represents the freezing point depression. To calculate the freezing point depression, three essential parameters are needed and these parameters are Van’t Hoff’s Factor (i), cryoscopic constant (K_{f}), and molality.

The formula for calculating freezing point depression:

Î´T_{f}Â = iK_{f}Â x Molality

Where;

Î´T_{f} = Freezing point depression

i = Van’t Hoff’s Factor

K_{f} = cryoscopic constant

Molality

Let’s solve an example;

Find the freezing point depression when the van’t hoff’s factor is 12, the cryoscopic constant is 21 with a molality of 16.

Î´T_{f}Â = iK_{f}Â x Molality

That is, Î´T_{f}Â = (12 x 21) x 16

Î´T_{f}Â = 252 x 16

Î´T_{f} = 4032

Therefore, the **freezing point depression** is **4032 Â°C m ^{-1}.**
