MCQ
Which one of the following aqueous solutions will exhibit highest boiling point
  • A
    $0.015 M$  urea
  • B
    $0.01\,M\,KN{O_3}$
  • ✓
    $0.01\,M\,N{a_2}S{O_4}$
  • D
    $0.015\,M\,$glucose
✓

Answer

Correct option: C.
$0.01\,M\,N{a_2}S{O_4}$
c
(c)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.
$N{a_2}S{O_4} \to 2N{a^ + } + SO_4^{2 - }$
