Ch 8: Solutions

Watch video lessons on solutions and learn about electrolytes, molarity, molality, colligative properties and more. Our video lessons are short and engaging to make learning easy!

Solutions - Chapter Summary and Learning Objectives

The word 'solutions' doesn't just mean 'answers' - in chemistry, it also refers to one substance dissolved in another. Common examples include ammonia, many prepackaged beverages, tap water and even air. With solutions all around us, it's no wonder we study them.

In these lessons, we'll give you a solid foundation for stepping into the world of solutions by looking at topics like solubility, molarity, and colligative properties as well as showing you how to do all kinds of calculations that solutions demand. After completing these lessons, you should be able to:

• Understand what solutions are
• Name several different kinds of solutions
• Explain solubility and what affects it
• Calculate molarity, molality and dilutions
• Figure out molar mass using properties of solutions

Video Objective
