Observation :
Sugar crystals separate out. Inference :
The sugar syrup solution prepared is a saturated solution.
Therefore,
Additional amount of sugar cannot be dissolved in it at room temperature.
In a saturated solution,
There exists...
We have given,
The vapour pressure of pure water at 25°C = 18mm Hg.
After addition of non-electrolyte, the vapour pressure of water = 17.32 mm Hg.
Then,
lowering in vapour pressure = (18...
