Chapter 12, Problem 12.75QE

Interpretation Introduction

Interpretation:

The grams of sodium chloride present in one kilogram of water and the total molality of the solute particles have to be calculated.

Concept Introduction:

Freezing point depression:  The freezing point depression is proportional to the concentration of the yellow solid particles and is given by the equation,

  ${\text{ΔT}}_{\text{f}}{\text{=mk}}_{\text{f}}$

Here,

  ${\text{ΔT}}_{\text{f}}\text{=}$ Freezing point of the solution

  $\text{m=}$ Molal concentration of the yellow solid

  ${\text{k}}_{\text{f}}\text{=}$ Freezing point depression constant (depends on the solvent used).
