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 $ .
