What is depression of freezing point? Explain.
(N/A) The freezing point of a substance is defined as the temperature at which the vapour pressure of the substance in its liquid phase is equal to its vapour pressure in the solid phase.
When a non-volatile solute is added to a solvent,the vapour pressure of the solution decreases.
Consequently,the solution freezes at a lower temperature than the pure solvent.
This difference in freezing point is known as the depression of freezing point,denoted by $\Delta T_f$.
