What is the Freezing Point Depression Calculator & How does it work?

Freezing point depression is a colligative property that occurs when non-volatile solutes are dissolved in a solvent, lowering its freezing point. The extent of this depression depends on the molality of the solution and the molal freezing-point depression constant (K_f) of the solvent.

ΔT_f = i K_f m

ΔT_f = change in freezing point, i = van ‘t Hoff factor, K_f = molal freezing-point depression constant, m = molality of the solution

The van ‘t Hoff factor (i) accounts for the number of particles a solute dissociates into in solution. For example, i = 2 for NaCl because it dissociates into two ions (Na⁺ and Cl^–). The molality (m) is calculated as moles of solute per kilogram of solvent.
