About This Chapter
MTLE Chemistry: Acids & Bases - Chapter Summary
Lessons in this chapter explore acids and bases, including the Arrhenius definition of bases and acids, neutralization and autoionization of water. The pH scale, acidic and basic salt solutions, and weak acids and bases are also covered. Additionally, by the end of this chapter, you should be prepared for any MTLE Chemistry exam questions that deal with the following:
- Acid and base anhydrides
- Acid-base equilibrium
- Acid-base buffers
- How pH is determined during titration
Knowledgeable instructors thoroughly explain each subject through short, engaging video lessons. Self-assessment quizzes can be used to test your knowledge, or print them as worksheets to help you study. The jump feature under the Timeline tab allows you to skip directly to main subjects within the video lessons.
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. 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.
