ΔTf=Kf·m freezing depression · boiling elevation

Quick Answer

Colligative Properties Calculator: ΔTf=Kf·m freezing depression · boiling elevation. Colligative Properties Calculator uses standard science & engineering formulas to compute accurate results instantly.

How it works

  1. 1ΔTf=Kf·m / ΔTb=Kb·m — depends only on particle count
  2. 2Water: Kf=1.86, Kb=0.512 (other solvents differ)
  3. 3Electrolytes multiply by van't Hoff i: NaCl≈2, CaCl₂≈3
  4. 4Road salt, antifreeze and pressure cooking exploit each side

Solution parameters

mol/kg
(nonelectrolyte=1)
Freezing depression ΔTf1.86°C
New freezing point：-1.86 °C
New boiling point：100.51 °C
Colligative effects count particles: 1 mol sucrose vs 1 mol NaCl (≈2 mol particles) differ ~2×. Road salt fades below −9 °C (CaCl₂ works colder); ethylene-glycol antifreeze uses depression + elevation together; seawater freezes near −2 °C for the same reason. At high concentration ideal-solution assumptions break down — treat results as estimates.
