Ch 19: General Science: Solutions & Solubility Factors

About This Chapter

Refresh your understanding of solutions and solubility factors by reviewing the short video lessons in this chapter. The videos and additional resources can strengthen your preparation for the NES General Science test.

AEPA General Science: Solutions & Solubility Factors - Chapter Summary

The state of Arizona has replaced the AEPA General Science test with the NES test. To increase your chances of success on the exam, you can review solutions and solubility factors lessons that ensure you're ready to:

  • Define and identify factors impacting the rate of dissolution
  • Describe solutions, electrolytes and nonelectrolytes
  • Explain solubility and solubility curves
  • Calculate molarity and molality concentration
  • Show how to calculate dilution of solutions
  • Exhibit how to use colligative properties to determine molar mass
  • Relate colligative properties to Raoult's law

The video lessons feature subject matter experts with a tremendous amount of insight into solutions and solubility factors. Review concepts you know and discover those you don't until you feel confident in your ability to answer related questions on the exam.

Objectives of the AEPA General Science: Solutions & Solubility Factors Chapter

As an educator in Arizona, you are required to take the NES General Science subject knowledge test to add this science endorsement to your teacher certificate and educate students in the classroom. The AEPA General Science: Solutions & Solubility Factors chapter gets you steps closer to earning a passing score of 220 or greater by exploring topics covered in the physical science content domain, which constitutes approximately 37% of the total exam.

The test is composed of 150 multiple-choice questions and is taken on computer. The self-assessment quizzes and practice exam in this chapter can test your comprehension of the lesson concepts while preparing you for questions formatted similarly to those you'll see on the exam.

Test your knowledge with a 30-question chapter practice test
The Rate of Dissolution: Factors and Definition

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.

Solutions, Electrolytes and Nonelectrolytes

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.

Solubility and Solubility Curves

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.

Calculating Molarity and Molality Concentration

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.

Calculating Dilution of Solutions

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.

Using Colligative Properties to Determine Molar Mass

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.

Colligative Properties and Raoult's Law

7. Colligative Properties and Raoult's Law

Learn how vapor pressure and osmotic pressure are colligative properties. Learn Raoult's Law and how to use it to determine the vapor pressure of a solution. Learn the equation for determining osmotic pressure and how to use it to determine the molar mass of a substance.
