MCQ

Which will show maximum depression in freezing point when concentration is $0.1\,M$

A
$NaCl$
B
Urea
C
Glucose
✓
${K_2}S{O_4}$

✓

Answer

Correct option: D.

${K_2}S{O_4}$

d
(d) $NaCl \to N{a^ + } + C{l^ - } = 2$ ions

${K_2}S{O_4} \to 2{K^ + } + SO_4^{2 - } = 3$ ions

${K_2}S{O_4}$ give maximum ion in solution so it shows maximum depression in freezing point.
