Solutions Question 71

Question: An aqueous solution of a non-electrolyte boils at $ {{100.52}^{o}}C $ . The freezing point of the solution will be

Options:

A) $ 0^{o}C $

B) $ -{{1.86}^{o}}C $

C) $ {{1.86}^{o}}C $

D) None of the above

Show Answer

Answer:

Correct Answer: B

Solution:

$ \Delta T_{b}=K_{b}\times m $ i.e. $ 0.52=0.52\times m $

$ \Delta T_{f}=K_{f}\times m=1.86\times 1=1.86 $ ; $ T_{f}=-{{1.86}^{o}}C $ .
