Colligative Properties of Solutions

Figure from experiment 12 from Investigating Chemistry through Inquiry

Introduction

Colligative properties of solutions ideally depend only on the number of solute particles per solvent molecule and not on the nature of the solute or solvent. Colligative properties include: vapor pressure lowering, freezing point depression, boiling point elevation, and osmotic pressure.

Objectives

In the Preliminary Activity, you will gain additional experience using a Temperature Probe as you determine the boiling point of water.

After completing the Preliminary Activity, you will first use reference sources to find out more about the colligative properties of solutions before you choose and investigate a researchable question dealing with the colligative properties of solutions.
