How Salt Melts Ice and Snow - ThoughtCo

Freezing point depression is a colligative property of water. A colligative property is one which depends on the nuer of particles in a substance. All liquid solvents with dissolved particles (solutes) demonstrate colligative properties. Other colligative properties include boiling point elevation, vapor pressure lowering, and osmotic pressure.
