Freezing Point Depression

Calculate how much a dissolved solute lowers a solvent's freezing point.

Molality (mol/kg)

Kf (default 1.86)

van't Hoff factor i (default 1)

Pure Solvent Freezing Point °C (default 0)

Freezing point depression ΔT = i·Kf·m. Defaults are for water (Kf = 1.86 °C·kg/mol, freezing at 0 °C) and a non-dissociating solute (i = 1).
