Q. Which of the following solutions will have the highest boiling point ?
A) 0.1 M $FeCl_{3}$
B) 0.1 M $BaCl_{2}$
C) 0.1 M NaVl
D) 0.1 M urea
Explanation
(a)
0.1 M $FeCl_{3}$ will give the maximum number of particles (i.e.,ions) in the solution. Hence, its elevation in boiling point is maximum and therefore, it has highest boiling point.
$FeCl_{3} \rightleftharpoons Fe^{3 +} + 3Cl^{-}$
