Chapter 13, Problem 13.79P

Interpretation Introduction

Interpretation:

The non-volatile electrolyte and the reason for its use to demonstrate the colligative properties are to be determined.

Concept introduction:

The solute is the substance that is present in smaller quantity and itself gets dissolved in some other substance. Colligative properties are the properties of a solution that depend on the concentration of solute and not on the identity of the solute.

The colligative properties are as follows:

1. Relative lowering of vapor pressure.

2. Elevation of boiling point.

3. Depression of freezing point.

4. Osmotic pressure.

The nonelectrolytes are the substances that do not form ions in the solution. So they cannot conduct electricity. There is the presence of covalent bonds in nonelectrolytes. Glucose $\left({\text{C}}_6{\text{H}}_{12}{\text{O}}_6\right)$ is an example of a nonelectrolyte.
