Ch 10: MTEL Chemistry: Acids & Bases

About This Chapter

Utilize the video lessons in this chapter to study acids and bases and review the pH scale. This information will be vital in helping you prepare for the MTEL Chemistry exam.

MTEL Chemistry: Acids & Bases - Chapter Summary

The lessons in this chapter have been developed to give you an in-depth overview of the pH scale and the fundamentals of acids and bases. Specifically, this chapter will address neutralization, anhydrides, titration, and how to calculate the pH of a buffered solution. Additionally, after completing the lessons in this chapter you will have reviewed:

  • The Arrhenius definition of acids and bases
  • Acid based reactions
  • Autoionization of water
  • Calculating pH and pOH
  • Acidic and basic salts
  • Weak acids and bases
  • Determining the Ka or Kb of a solution

Each video lesson has been developed by professionals in the field to best assist you in retaining the information. There is a timeline below each video in case you need to return to a particular section to review the information. Take the self-assessment quizzes at the end of each lesson to gauge your ability to apply your knowledge of the topic.

MTEL Chemistry: Acids & Bases - Objectives

The MTEL (Massachusetts Tests for Educator Licensure) Chemistry exam assesses whether or not a prospective educator meets the standard qualifications required to teach chemistry courses in Massachusetts. The chemistry exam is scored based on 4 content subareas, and the information reviewed in this lesson will prepare you for questions related to chemical reactions and solutions, which account for 20% of the final score.

The MTEL Chemistry exam is a computer-based test that consists of 100 multiple-choice questions and 2 open-ended questions. The 2 open-ended questions account for 20% of the total score and could be related to any of the 4 subareas so it is essential to prepare for all of them. A score of 240 or higher is needed to qualify for professional certification.

The Arrhenius Definition of Acids and Bases

1. The Arrhenius Definition of Acids and Bases

In this lesson, you will learn the definition of Arrhenius acids and bases, discover some of their chemical properties and learn some examples. You will also learn about the difference between strong and weak Arrhenius acids and bases.

Neutralization and Acid-Base Reactions

2. Neutralization and Acid-Base Reactions

From this lesson, you will understand the neutralization process between acids and bases. Learn how a hydroxide ion from a base reacts with a hydronium ion from an acid to neutralize each other and form water. Discover what conjugate acids and bases are and what the definition of amphoteric is.

Dissociation Constant and Autoionization of Water

3. Dissociation Constant and Autoionization of Water

Learn the meaning of auto-ionization of water, sometimes called self-ionization, where water acts as a proton donor and acceptor to form both hydronium and hydroxide ions. Learn what the auto-ionization constant is and how to use it to determine the concentration of either hydroxide or hydronium ions in a solution when given the other value.

The pH Scale: Calculating the pH of a Solution

4. The pH Scale: Calculating the pH of a Solution

Learn the history of the pH scale, how to describe it and why it is used by scientists. Discover how to calculate the pH of an acid or base solutions given either the hydroxide ion concentration or the hydronium ion concentration. Learn how to start with the pH and calculate the hydroxide and hydronium ion concentrations.

Acidic & Basic Salt Solutions: Explanation & Examples

5. Acidic & Basic Salt Solutions: Explanation & Examples

In this video lesson, you will learn how to tell if a salt solution is acidic, basic, or neutral. You will find out how to recognize the effect of individual ions in solution and how they can change the pH. A short quiz will test your knowledge.

Weak Acids, Weak Bases, and Buffers

6. Weak Acids, Weak Bases, and Buffers

This lesson covers both strong and weak acids and bases, using human blood as an example for the discussion. Other concepts discussed included conjugate acids and bases, the acidity constant, and buffer systems within the blood.

Acid & Base Anhydrides: Definition & Examples

7. Acid & Base Anhydrides: Definition & Examples

In this video lesson, you will learn the definition and the types of anhydrides that form acids and bases in water. You will also discover where you can commonly find anhydrides and why they are important. A short quiz will test your knowledge.

Acid-Base Equilibrium: Calculating the Ka or Kb of a Solution

8. 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.

Acid-Base Buffers: Calculating the pH of a Buffered Solution

9. 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.

Titration of a Strong Acid or a Strong Base

10. 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.

Titration: Overview, Curves & Calculations

11. Titration: Overview, Curves & Calculations

Titrations are useful to determine the molarity of a sample or a compound in a sample. We will learn how to perform a titration and how to calculate the molarity of a sample based on the titration.
