Question

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

• A. $1.0MNaOH$
• B. $1.0MN{a}_{2}S{O}_4$
• C. $1.0MN{H}_{4}N{O}_3$
• D. $1.0MKN{O}_3$

Answer 1

Answer: (B)

$T_b\propto$ number of particles of solute.

$N{a}_{2}S{O}_4->2N{a}^{+}+S{O}_4^{2-}$

$\Rightarrow 3$ particles
