Which amongst the following aqueous solutions of electrolytes will have minimum elevation in boiling point? Choose the correct option.
  1. $0.1 \mathrm{M} \mathrm{MgSO}_4$
  2. $1 \mathrm{M} \mathrm{NaCl}$
  3. $0.05 \mathrm{M} \mathrm{NaCl}$
  4. $0.1 \mathrm{M} \mathrm{KCl}$

Solution

$\begin{array}{ll}\text { Solution } & \text { Moles of particles in } 1 \mathrm{~L} \text { solution } \\ 0.1 \mathrm{M} \mathrm{MgSO}_4 & 0.2 \\ 1 \mathrm{M} \mathrm{NaCl} & 2 \\ 0.05 \mathrm{M} \mathrm{NaCl} & 0.1 \\ 0.1 \mathrm{M} \mathrm{KCl} & 0.2\end{array}$ Lesser is the number of particles, lower is the elevation in boiling point
