What is Delta T = K_f × m?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
This is the freezing point depression formula:
- ΔT = freezing point lowering (°C)
- K_f = cryoscopic constant (specific to solvent)
- m = molality of solution (mol/kg)
For boiling point elevation: ΔT = K_b × m
These colligative properties depend on solute concentration, not identity.
