Q. Which one of the following aqueous solutions will exhibit highest boiling point?
A) $0.01\ M\ Na_{2}SO_{4}$
B) $0.01\ M\ KNO_{3}$
C) 0.015 M urea
D) 0.015 M glucose
Explanation
(a)
Elevation in boiling point is a colligative property which depends upon the number of solute particles. Greater the number of solute particle in a solution higher the extent of elevation in boiling point. $Na_{2}SO_{4}$, gives maximum ions hence, it exhibits highest boiling point
