Question

Which of the following has the highest freezing point? (A) 1 m NaCl solution (B) 1 m KCl solution (C) 1 m AlCl3 solution (D) 1 m C6H12O6 solution

Tardigrade Admin · Accepted Answer

C6H12O6 is a non-electrolyte hence furnishes minimum number of particles and will have maximum freezing point. Δ Tf = iKfm or Δ Tf propto i and Δ Tf = T°f - Tf

Q. Which of the following has the highest freezing point?

$1 m N a Cl$ solution

$1 m K Cl$ solution

$1 m A lC l_{3}$ solution

$1 m C_{6} H_{12} O_{6}$ solution

$C_{6} H_{12} O_{6}$ is a non-electrolyte hence furnishes minimum number of particles and will have maximum freezing point.
$Δ T_{f} = i K_{f} m$ or $Δ T_{f} \propto i$ and $Δ T_{f} = T_{f}^{\circ} - T_{f}$
