During the depression in freezing point experiment, an equilibrium is established between the molecules of
Options
- Aliquid solvent and solid solvent
- Bliquid solute and solid solvent
- Cliquid solute and solid solute
- Dliquid solvent and solid solute
Correct answer
A. liquid solvent and solid solvent
Step-by-step solution
Freezing point of a substance is the temperature at which the solid and the liquid forms of the substance are in equilibrium. If a non-volatile solute is added to the solvent, there is decrease in vapour pressure of the solution and thus the freezing point of the solution is less than that of pure solvent. It is called depression in freezing point.
