About This Chapter
TExES Chemistry: Types & Properties of Solutions - Chapter Summary
The lessons in this chapter are designed to enhance your understanding of the types of solutions and the chemical processes that affect solutions. Review electrolytes, solubility and more! After viewing the lessons, you should be able to successfully demonstrate the following abilities as you prepare to take the TExES Chemistry test:
- Identify the factors that influence dissolution
- Detail solutions, nonelectrolytes and electrolytes
- Explain solubility and solubility curves
- Calculate molarity and molality concentration
- Find the dilute of a solution
- Determine molar mass using colligative properties
- Define the properties of water
Video lessons use simple and direct language to explain complex chemistry topics, making it easy and fun to review the material. Quizzes are presented in the same multiple-choice format as you will find on the actual TExES exam. Help from one of our experts is available via the Dashboard.
1. The Rate of Dissolution: Factors and Definition
Learn what dissolution is and the factors that affect the rate of dissolution, such as temperature, surface area, polarity and pressure. Learn what miscible and immiscible mean in regards to liquids.
2. Solutions, Electrolytes and Nonelectrolytes
Learn what a solution is and how it is formed. Learn how to express the concentration of a solution in terms of molarity, molality and mass percent. Discover the differences between an electrolyte and a nonelectrolyte.
3. Solubility and Solubility Curves
Learn what solubility is as well as the definitions of 'saturated,' 'unsaturated' and 'supersaturated.' Learn how to determine the solubility of a substance in water by using a solubility curve. Discover the effects of pressure and temperature on the solubility of liquids, solids and gases.
4. Calculating Molarity and Molality Concentration
Learn the abbreviations and meaning of molarity and molality. Then apply what you have learned by going over some sample calculations with given concentrations.
5. Calculating Dilution of Solutions
Learn what a solution is and how to properly dilute a new solution from a stock solution. Learn the dilution equation that combines molarity, the volume of stock solution and desired solution to determine how much stock solution is needed for the new solution.
6. Using Colligative Properties to Determine Molar Mass
In this lesson, we will explore the effect of colligative properties on a solution. We will learn how to calculate freezing point depression and see how it can be used to calculate the molar mass of an unknown substance.
7. Properties of Water
Why does ice float? Why can water rise on its own against gravity in a small tube? Find out how these mysterious properties of water can be explained by hydrogen bonds.
