Question

During the specific experimental measurement of colligative properties, specifically the depression of freezing point ($\Delta T_f$) in a standard binary solution, which of the following physical phases are strictly in dynamic thermodynamic equilibrium precisely at the freezing temperature?

Prashant Kotian · Accepted Answer

Correct answer: A,B. The freezing point of a solution is defined thermodynamically as the temperature at which the vapour pressure of the liquid solvent in the solution exactly equals the vapour pressure of the pure solid solvent. Thus, dynamic equilibrium is established purely between the liquid solvent component of the solution and the solid solvent precipitating out.
