Overview

Polar solutes tend to dissolve in polar solvents; nonpolar solutes tend to dissolve in nonpolar solvents. However, the dissolving nature also depends on the charge of the ions in the solution. Non-polar substances have Van der Waals attractions which are weak but present.

Learning objectives

After completing this module, you will be able to:
- Identify water as a polar solvent.
- Identify ethanol as a polar solute.
- Identify sodium chloride as an ionic solute.
- Identify hexane as a nonpolar solvent.
- Identify pentane as a nonpolar solute.
- Describe the process of dissolving a polar solute in a polar solvent.
- Describe the process of dissolving an ionic solute in a polar solvent.
- Describe the process of dissolving a nonpolar solute in a nonpolar solvent.
