Chemistry - Liquid Solution Question with Solution | TestHub

The freezing point of 1 molal NaCl solution assumtextng NaCl to be 100% dissociated in water is -

$∆{\text{T}}_{\text{f}}=\text{i}\times {\text{K}}_{\text{f}}\times \text{m}$

$=2\times 1.86\times 1={3.72}^{\text{o}}\text{C}$

Freezing point = (0-3.72)$= \; -{3.72}^{\text{o}}\text{C}$
