MCQ
Which of the following aqueous solutions should have the highest boiling point?
  • A
    $\text{1.0M NaOH}$
  • ✓
    $\ce{1.0M Na_2SO_4}$
  • C
    $\ce{1.0M NH_4NO_3}$
  • D
    $\ce{1.0M KNO_3}$
✓

Answer

Correct option: B.
$\ce{1.0M Na_2SO_4}$
In $\ce{1.0M Na_2SO}_4$ solution vant $H$ off factor$, i > 1$ and is maximum when compared with the other three given electrolytes. So, the extent of dissociation in case of $\ce{1.0M Na_2SO_4}$ would be highest yielding maximum no. of ions as compared to the other given electrolytes in their $1.0M$ solutions.
