Ch 13: MEGA Chemistry: Acids & Bases

About This Chapter

Watch short video lessons to increase your knowledge of acids and bases as you study for the MEGA Chemistry assessment. Expert instructors help you get reacquainted with the Arrhenius definition, the pH scale, acid-base equilibrium and more.

MEGA Chemistry: Acids & Bases - Chapter Summary

You can eliminate the overwhelming feeling often associated with studying for a certification test like Missouri's MEGA Chemistry by reviewing the lessons in this chapter. Gain greater insight into acids and bases to ensure you're prepared for the following on exam day:

  • Explaining the Arrhenius definition of acids and bases
  • Analyzing neutralization and acid-base reactions
  • Defining auto-ionization of water, and explaining how to calculate the pH or pOH of a solution
  • Discussing acidic and basic salt solutions, weak acids, weak bases and buffers
  • Sharing the meaning of acid and base anhydrides
  • Calculating the Ka or Kb of a solution, and the pH of a buffered solution
  • Describing the titration of a strong acid or strong base

Instructors in the lessons provide you with definitions, explanations and examples you can use to fully comprehend acids and bases. Review the lessons as videos or transcripts with easily identifiable vocabulary words, and revisit them as often as needed. At any point, feel free to take the self-assessment quiz with each lesson, or the chapter exam, to gauge your readiness for the test.

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.
