Solutions and Colligative Properties

Resources on these topics pages are here to assist you in your mastery of course content. None of the work, etc, on these pages are 'required,' so to speak. It is provided for you to use as fits into your overall approach to studying for this course. 

• General and detailed objectives give you an idea of how you will be assessed over each objective and can serve as a 'study guide' of sorts

• Slides are the raw material from which I build my in-class lectures. Annotated slides will be provided after lectures on the course schedule.

• When available, Reading Guides are provided to assist you in taking and organizing notes as you read the textbook. 

• Any supplemental videos provided are produced by myself other chemistry education professionals.

• Any additional practice provided contains answer keys, so that you may check your work.

Solutions and Colligative Properties Objectives

1. Describe the basic process of dissolution

2. Explain what an electrolyte is and the interactions they have in solution

3. Discuss the factors that affect solubility

4. Define colligative properties and discuss their effect on the properties of solutions

Objective 1: Describe the basic process of dissolution
