Question

During depression of freezing point in a solution the following are in equilibrium:

• A. liquid solvent, solid solvent
• B. liquid solvent, solid solute
• C. liquid solute, solid solute
• D. liquid solute, solid solvent

Answer 1

Answer: (A)

liquid solvent, solid solvent

Freezing-point depression is the process in which adding a solute to a solvent decreases the freezing point of the solvent.

When you add solid particle in a liquid it hinders the interparticle attraction of the liquid particles , that's why their freezing point decrease .

Now, what happen at freezing point , the liquid and solid form of a substance must be in equilibrium , so answering to your question ,

The liquid solvent and solid solvent form are in equilibrium.
