Q. Which of the following solution highest boiling point?
A) 0.1 M urea
B) 0.1 M sucrose
C) 0.1 M $NaNO_{3}$
D) 0.1 M $Al(NO_{3})_{3}\$
Explanation
(d)
Elevation in boiling point is a colligative property, which depends upon the nmber of particles in solution. $Al(NO_{3})_{3}$ give maximum ions (4 ions) in solution, hence , its elevation in boiling point will be the highest. Hence, boiling point of 0.1 M $Al(NO_{3})_{3}$ solution will be the highest.
