About This Chapter
Overview of Acids - Chapter Summary
By working through these lessons, you can deepen your knowledge of acids. Some of the topics covered include the pH scale and acid-base equilibrium. This comprehensive chapter can also help you review common acids used in laboratories. After completing the lessons, you should be ready to:
- Differentiate between monoprotic and polyprotic acids
- Explain self-ionization of water
- Discuss how the pH or pOH of a solution is calculated
- Provide examples of strong and weak acids
- List properties of concentrated and dilute acids
- Recall how the Ka or Kb of a solution is calculated
- Discuss the strengths of common acids
These lessons can help you quickly absorb concepts related to acids, with key terms and definitions set off in bold font for easy reference. A brief quiz is available to gauge your knowledge of each lesson, and the quizzes can be printed for use as an additional study tool. This online learning platform offers the flexible of studying when it's convenient for you.
1. Monoprotic and Polyprotic Acids
Deduce the difference between monoprotic and polyprotic acids, then learn about how acids break apart and what that means for acid strength. Then, assess your new knowledge with a quiz.
2. 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.
3. 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.
4. Strong Acid: Definition & Examples
Acids are very common in nature and in chemical reactions. In this lesson, you will learn what makes a substance an acid and how to recognize strong acids from others.
5. Weak Acids: Properties & Examples
Whether you realize it or not, you eat or use weak acids on an everyday basis. In this lesson, you'll learn about the definition and properties of weak acids and become familiar with some examples.
6. Concentrated & Dilute Acids: Properties & Examples
In this lesson, we describe how to differentiate between dilute and concentrated acid solutions. We will discuss several example problems with calculations.
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. Common Acids Used in Industry & Laboratories
In this lesson, you will learn about five of the most common acids used in labs and in industry: sulfuric acid, nitric acid, hydrochloric acid, citric acid and acetic acid.
9. Common Acids: Strengths & Ionization
What determines the strength of an acid? In this lesson, you will learn how acids dissociate in water and how chemists use this phenomenon to classify the strength of an acid.
