Ch 9: OAE Chemistry: Solutions & Solubility

About This Chapter

This chapter presents all the essential topics related to solutions and solubility in short video lessons. You'll easily get up to speed on the calculations, rates and properties you'll need to be familiar with to answer questions about solutions and solubility on the OAE Chemistry exam.

OAE Chemistry: Solutions and Solubility - Chapter Summary

The lessons in this chapter provide a fresh look at the calculations for molarity and molality and dilution of solutions that you'll need for the OAE exam. You'll also find lessons on related topics, including:

  • Factors that affect the rate of dissolution
  • Electrolytes and nonelectrolytes
  • Solubility curves
  • Methods for predicting reaction outcomes
  • Use of colligative properties to determine molar mass
  • Solubility of gases in a liquid

Professional instructors break down large concepts into short, easily digestible chunks that help you quickly retain critical info for the exam. Our video format offers flexibility since you can watch lessons from any location at any time using your mobile device.

OAE Chemistry: Solutions and Solubility - Chapter Objectives

Before you can get certified to teach chemistry in Ohio, you'll need to take the OAE subject exam in chemistry. This exam has 150 questions across five different domains that test your knowledge of chemistry concepts, including solutions and solubility. These topics are asked about in the stoichiometry and solutions domain, which represents 18% of the exam. You might be given a formula and asked to perform calculations in order to select the best response or you might have to read a passage and answer questions about it, selecting the most appropriate response from a series of options. Our self-assessment quizzes are a useful tool for helping you prepare for the style of questions you'll find on the exam.

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.

Solubility of Common Salts: Predicting Reaction Outcomes

4. Solubility of Common Salts: Predicting Reaction Outcomes

Ever wondered why some salts dissolve in water and others don't? In this lesson you will learn about some simple salt solubility rules. Using these rules, you will be able to predict the products of many chemical reactions.

Calculating Molarity and Molality Concentration

5. 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

6. 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.

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.

Using Colligative Properties to Determine Molar Mass

8. 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.

The Solubility of Gases in a Liquid

9. The Solubility of Gases in a Liquid

In this video lesson, you will learn what solubility is and the factors that affect gas solubility. We will use real-life examples to illustrate the importance of understanding solubility. A quick quiz will then test our new knowledge.
