About This Chapter
TExES Chemistry: Equilibrium - Chapter Summary
Using these video lessons can help you develop a deeper understanding of calculating, measuring and identifying the equilibrium of chemical solutions. You will also learn about factors that impact this equilibrium. Once you have mastered this material, you will be able to demonstrate the following and be prepared to take the TExES Chemistry exam:
- Explaining LeChatelier's Principle of equilibrium
- Using a RICE table to calculate equilibrium
- Discussing aspects of solubility
- Defining the common ion effect
- Understanding acid and base dissociates
- Calculating the pH of a buffer solution
- Applying the concept of titration
The use of detailed examples and simple language make reviewing this material fun and easy. You can prepare to take the TExES Chemistry exam by completing the accompanying quizzes following each lesson, which use the same multiple-choice format you will encounter on the actual exam.
TExES Chemistry: Equilibrium Objectives
TExES are state-educator exams that result in teacher certification in specific content areas. The exams are used to test a teacher's knowledge of standards within each content area. Teachers can obtain certification at the elementary, middle or high school levels.
The Equilibrium chapter will help you review material you will be tested on when taking the TExES Chemistry exam for 7-12 grade students. The exam contains 100 multiple-choice questions and is administered by computer. The lessons will help you demonstrate proficiency in topics regarding chemical solution equilibrium and factors that impact this equilibrium. You must score at least 240 to pass this or any other TExES exam.
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
