The properties of the solutions which depend only on the number of solute particles but not on the nature of the solute are called colligative properties. Relative lowering in vapour pressure is also an example of colligative properties. For an experiment, sugar solution is prepared for which lowering in vapour pressure was found to be 0.061 mm of Hg. ( Vapour pressure of water at 20•C is 17.5 mm of Hg)?

Explanation of Relative Lowering in Vapour Pressure:
Lowering in vapour pressure is a colligative property that depends on the number of solute particles in a solution, not on the nature of the solute itself.
Given Information:
- Vapour pressure of water at 20°C = 17.5 mm of Hg
- Lowering in vapour pressure of a sugar solution = 0.061 mm of Hg
Calculation:
The relative lowering in vapour pressure can be calculated using the formula:
Relative Lowering in Vapour Pressure = (Lowering in Vapour Pressure of Solution) / (Vapour Pressure of Pure Solvent)
Plugging in the values:
Relative Lowering in Vapour Pressure = 0.061 mm of Hg / 17.5 mm of Hg
Relative Lowering in Vapour Pressure ≈ 0.0035
This means that the vapour pressure of the sugar solution is approximately 0.35% lower than the vapour pressure of pure water at 20°C.
Conclusion:
The relative lowering in vapour pressure of a sugar solution indicates the extent to which the presence of sugar molecules in the solution affects the evaporation rate of water molecules. This phenomenon is a direct consequence of the colligative properties of solutions.
