During the depression in freezing point experiment, an equilibrium is established between the molecules of
Show Hint
Freezing point corresponds to equilibrium between liquid and solid phases of the solvent only. Solute stays in liquid phase.

The Correct Option is A
Solution and Explanation
Step 1: Understand freezing point depression.
Freezing point is the temperature at which solid and liquid phases of the solvent coexist in equilibrium.
Step 2: What equilibrium exists at freezing point?
At freezing point:
\[ \text{liquid solvent} \rightleftharpoons \text{solid solvent} \]
Solute does not form solid phase at that stage; the solid formed is pure solvent.
Step 3: Conclusion.
Therefore, equilibrium is established between liquid solvent and solid solvent molecules.
Final Answer:
\[ \boxed{\text{liquid solvent and solid solvent}} \]
