Question

'The presence of non-volatile impurity lowers the freezing point of a liquid.'
Explain the statement ​

Answer 1

Answer:

Explanation:

Explanation. The freezing point is the temperature at which the liquid solvent and solid solvent are at equilibrium, so that their vapour pressures are equal. When a non-volatile solute is added to a volatile liquid solvent, the solution vapour pressure will be lower than that of the pure solvent.
