What is the equation for freezing point? Chemistry Solutions Colligative Properties 1 Answer Sarita Rana Feb 14, 2017 #ΔTf# = #Kf# . #m# Explanation: Where #ΔTf# = the freezing-point depression #ΔTf# = #Tf# (pure solvent) − #Tf# (solution). #Kf# = the cryoscopic constant, which is dependent on the properties of the solvent, not the solute. #m# = molality of the solution Answer link Related questions How are colligative properties determined?
