Ch 15: ORELA Chemistry: Solutions in Chemistry

About This Chapter

As you get set to take the ORELA Chemistry examination, build upon your knowledge of solutions in chemistry. The video lessons in this chapter will allow you to revisit this topic or learn entirely new information.

ORELA Chemistry - Equilibrium - Chapter Summary

The online tutorial videos in this chapter will enhance your knowledge of LeChatelier's Principle, solubility constant, the RICE table and other topics. For instance, you'll recall how to make equilibrium concentrations and determine ksp values as you prepare to perform similar operations on the ORELA Chemistry examination. Look to this chapter for assistance with:

  • Comparing chemical and dynamic equilibrium
  • Explaining LeChatelier's Principle
  • Defining equilibrium constant and reaction quotient
  • Filling in a RICE table
  • Discussing solubility equilibrium
  • Describing the common ion effect

Comprised of short video lessons, this chapter will allow you to review what you already know about equilibrium and to possibly discover additional information. Along with written transcripts, the chapter includes pop-up quizzes, navigational video tags and printable worksheets. Experienced instructors provide the narration, and they answer your interactively submitted questions.

ORELA Chemistry - Equilibrium Objectives

Demonstrate what you learned about equilibrium previously and what you reviewed in this chapter when you get to the ORELA Chemistry examination's Chemical Reactions content domain. This content domain accounts for about 23% of the exam's total score. It will test your knowledge of equilibrium principles and ensure your in-depth knowledge of chemical equilibrium and its influence. Display this understanding while answering the 150 multiple-choice questions on the computer-based assessment. As a candidate for a chemistry teaching endorsement, you must observe a three-hour-and-45 minute time limit when testing.

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.
