OAE Chemistry: Acids & Bases - Chapter Summary
Before you register for the OAE Chemistry exam, refresh your memory on weak and strong acids and bases, titrations and the pH scale with short and dynamic videos. Each lesson presents a concept you could be asked about on the exam, such as:
- Acid-base reactions and neutralization
- Autoionization of water
- pH and pOH calculations of solutions
- Weak acids, bases and buffers
- Calculations of the Ka or Kb of a solution and pH of a buffered solution
- Titrations of strong and weak acids and bases
These videos offer a convenient way to quickly re-learn topics you studied in college as you prepare for the exam. You'll find transcripts that you can use to easily locate vocabulary words and definitions, as well as video tags that let you review the main points of each video.
OAE Chemistry: Acids & Bases - Chapter Objectives
Ohio's teacher licensing process includes subject tests for aspiring teachers in specific fields, such as chemistry. The OAE Chemistry test gauges your knowledge of matter, atomic structure, chemical bonding and reactions, energy, solutions and stoichiometry. You'll be tested on acids and bases in the chemical reactions domain, which covers about 23% of the exam's 150 questions. The multiple-choice format of this exam is mirrored in the quizzes that follow each of our lessons. Use these quizzes to test your understanding of acids and bases and to get familiar with the format of the exam questions.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
11. 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.
