The formula to calculate the Freezing Point Depression is:
\[ Tf = Kf \times b \times i \]
Where:
Freezing point depression is a property observed in solutions that describes the effect of a solution’s freezing point being lower than that of a pure solvent. The freezing point is directly related to the molality of the solute. This phenomenon occurs because the presence of solute particles disrupts the formation of the solid phase, requiring a lower temperature to achieve the same state as the pure solvent.
Let's assume the following values:
Using the formula:
\[ Tf = 1.86 \times 2 \times 1 = 3.72 \]
The Freezing Point Depression (Tf) is 3.72.
