Solutions Question 78
Question: Which will show maximum depression in freezing point when concentration is 0.1M [IIT 1989; MNR 1990; UPSEAT 2000; 03; BCECE 2005]
Options:
A) NaCl
B) Urea
C) Glucose
D) $ K_2SO_4 $
Show Answer
Answer:
Correct Answer: D
Solution:
$ NaCl\to N{a^{+}}+C{l^{-}}=2 $ ions $ K_2SO_4\to 2{K^{+}}+SO_4^{2-}=3 $ ions $ K_2SO_4 $ give maximum ion in solution so it shows maximum depression in freezing point.
