About This Chapter
Who's it for?
This unit of our AP Chemistry Homeschool course will benefit any student who is trying to learn about how chemical equilibrium is maintained and measured. There is no faster or easier way to learn about equilibrium. Among those who would benefit are:
- Students who require an efficient, self-paced course of study to learn what equilibrium is, what factors affect it, and how equilibrium (or a lack of equilibrium) is measured in chemical solutions.
- Homeschool parents looking to spend less time preparing lessons and more time teaching.
- Homeschool parents who need a chemistry curriculum that appeals to multiple learning types (visual or auditory).
- Gifted students and students with learning differences.
How it works:
- Students watch a short, fun video lesson that covers a specific unit topic.
- Students and parents can refer to the video transcripts to reinforce learning.
- Short quizzes and an equilibrium unit exam confirm understanding or identify any topics that require review.
Equilibrium Unit Objectives:
- Define chemical and dynamic equilibrium.
- Discuss the ways in which equilibrium can be disrupted.
- Identify why the equilibrium constant and equilibrium quotient are important.
- Demonstrate how to calculate equilibrium using a RICE table.
- Define solubility equilibrium.
- Understand the common-ion effect and equilibrium calculations with a common ion.
- Explain how to calculate the acidity or basicity of a solution.
- Discover acid-base buffers and how they work in a buffered solution.
- Calculate the pH of a titration composed of a strong acid and strong base.
- Describe how a titration curve works.
1. Equilibrium: Chemical and Dynamic
Learn the definition of chemical equilibrium and how it is dynamic. Discover what the equilibrium constant is and how it shows whether the reaction favors the reactants or products. Learn how chemists designate equilibrium in an equation and how they show the difference in reaction rate.
2. LeChatelier's Principle: Disruption and Re-Establishment of Equilibrium
Learn how Le Chatelier's Principle describes the disruption and re-establishment of equilibrium. Learn to explain the factors that disrupt equilibrium, such as concentration, temperature, and pressure. Learn how each of these factors affects a system in equilibrium.
3. Equilibrium Constant (K) and Reaction Quotient (Q)
In this lesson, we will first define and explain the notion of a chemical equilibrium. Then, you'll learn about the equilibrium constant and reaction quotient. Finally, we'll round off the lesson with a couple of examples to solidify what you've learned!
4. Using a RICE Table in Equilibrium Calculations
Learn what the RICE table is and how to fill in the table with the reaction, initial concentration, change in concentration and amount of product and reactants at equilibrium. Learn how to use the RICE table to calculate the concentrations and amounts and the equilibrium constant of equations at equilibrium.
5. Solubility Equilibrium: Using a Solubility Constant (Ksp) in Calculations
Learn the definition of solubility and solubility constant (Ksp) in this lesson. Interpret solubility constants and make calculations involving the dissociation of a slightly soluble compound given molar solubility.
6. The Common Ion Effect and Selective Precipitation
Learn what the common ion effect is, how to make equilibrium calculations involving it, and how to find the concentrations of ions when adding reactions in equilibrium to solutions that already contain ions.
7. Acid-Base Equilibrium: Calculating the Ka or Kb of a Solution
In this lesson, you will review acid and base strength and acid and base dissociation. You will then learn what acid and base dissociation constants (Ka and Kb) are, what they mean, and how to perform calculations involving them.
8. Acid-Base Buffers: Calculating the pH of a Buffered Solution
Learn what a buffer is, how it works, and why we benefit from having our blood buffered. Learn how to calculate the pH of a buffered solution before an acid or base is added and how the pH changes after an acid or base is added.
9. Titration of a Strong Acid or a Strong Base
Discover what titration is and how to calculate the concentration of an acid or base that has been titrated to equivalence. Learn the meaning of titrant, standard solution and equivalence point. Study titration curves and learn how to determine pH during any point of a titration between a strong acid and strong base.
10. Titrations with Weak Acids or Weak Bases
Learn about titrations with weak acids or weak bases in this lesson. Study their titration curves and learn about some of their important characteristics. Learn how to calculate pH during titrations involving weak acids and strong bases.
