Which of the following aqueous solutions should have the highest boiling point ?

$1.0 \, M \, NaOH$

$1.0 \, M \, Na_{2}SO_{4}$

$1.0 \, M \, NH_{4} NO_{3}$

$1.0 \, M \, KNO_{3}$

Answer

$1.0 \, M \, Na_{2}SO_{4}$

Explanation

$T_b \; \propto$ number of particles of solute.

$Na_2 SO_4 -> 2Na^{+} + SO^{2-}_4$
$\Rightarrow \,3$ particles
