Question

In the depression of freezing point it is found that-
1)the vapour pressure of solution is more than that of pure h2o
2)the vapour pressure of solution is more than that of pure solute 3)only solute molecules solidify at freezing point
4) only solvent molecules solidify at freezing point
And to the question is 4) but my doubt is why is option 2) not correct

Answer 1

Answer:

the answer is 4) only the solvent molecules solidify at freezing point

Explanation:

cause when the temperature decreases the liquid molecules get contract to each other which formed by freezing of solvent molecules
