# Ch 57: MTEL Middle School Math/Science: Equilibrium

### About This Chapter

## MTEL Chemistry: Equilibrium - Chapter Summary

Do you remember Le Chatelier's Principle? If you don't, you can watch a 5-10 minute video lesson to jog your memory. Use one of our chapter quizzes to gauge your understanding of the utilization of a RICE table. This chapter's study guides provide a strong foundation of chemistry concepts so that you can become an expert in answering exam questions about the following:

- Chemical equilibrium
- Le Chatelier's Principle
- Meaning of equilibrium constant (K)
- Usefulness of a RICE table
- Solubility equilibrium, acid-base equilibrium, and acid-base buffers
- Definition of the common ion effect
- Explanation of titration, weak acids, and weak bases

Not only does this chapter contain end-of-lesson quizzes, but it also includes practice chapter and final exams. Don't worry about tracking your progress through the chapter, because we do that for you. Also, if you would like to review specific parts of the video lessons, use the timeline underneath the videos.

### MTEL Chemistry: Equilibrium Objectives

The study resources found in this chapter will help you answer the MTEL Middle School Chemistry questions under the Thermodynamics category. The category is worth 20% of the entire MTEL Chemistry exam. Part of the 100 multiple-choice questions may ask you to demonstrate your understanding of Le Chatelier's Principle and equilibrium constant. Two-opened questions may also appear on the exam.

### 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.
