Chapter 12, Problem 94RQ

Interpretation Introduction

Interpretation:

The given data suggest that the formula of the mercury (I) ions is ${\text{Hg}}_{\text{2}}^{\text{2+}}$ is to be shown.

Concept Introduction:

The temperature at which substance changes from liquid state to solid state is called freezing point.

The freezing point depression is calculated by using the expression as follows:

$\Delta T_{\text{f}}=m\times i{K}_{\text{f}}$

Here, $i$ is the van’t Hoff factor, $\Delta T_{\text{f}}$ is the change in temperature of the freezing point in $\text{C}$, $m$ is the molality of the solution in $\frac{\text{mol of solute}}{\text{mass of solvent(kg)}}$, and $K_{\text{f}}$ is the freezing point depression constant for the solvent.
