Colligative Properties of Solutions
Recommended for grades 9–16.
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.
Sensors and Equipment
This investigation requires each of the following Vernier sensors and equipment (unless otherwise noted):
Additional Requirements
You may also need an interface and software for data collection. What do I need for data collection?
Download Experiment Preview
The student-version preview includes:
- Step-by-step instructions for the Preliminary Activity
- List of materials and equipment
Note: The experiment preview of the Preliminary Activity does not include essential teacher information, safety tips, or sample data. Instructions for Logger Pro and other software (such as LabQuest App or TI handheld software, where available) are on the CD that accompanies the book. We strongly recommend that you purchase the book before performing experiments.
