Chapter 6, Problem 6.75QP

Interpretation Introduction

Interpretation:

The freezing temperature of $0.50mNaCl$ and sucrose solution has to be calculated.

Concept Introduction:

Depression in freezing point:

At freezing point solid phase of the solvent will be in equilibrium with liquid phase.  When solute molecule is added, it will interfere with the rate at which the liquid molecules associate to form solid state, hence lower the freezing point of the solution.

    $\Delta T_f=k_f\left(mparticles\right)$

Where, $\Delta T_f$ difference in temperature of pure solvent and solution, $k_f$ is freezing point depression constant.
