Question

An aqueous solution of NaCl freezes below 273K Explain the
lowering in freezing point of water with the help of suitable
diagram

Manali · Answer

when sodium chloride is dissolved in water, the vapour pressure
of solution become less and at a lower temperature vapour pressure
of solid solvent and liquid solvent becomes equal i e lowering in
freezing point takes place
