About This Chapter

During those late-night study sessions for the Praxis Middle School Science exam, peruse these video lessons and determine the relationship between acids and bases. Comb through the key terms on the transcripts to get ready for exam questions.

Praxis Middle School Science: Acid-Base Chemistry - Chapter Summary

In the field of chemistry, acids and bases have very different scientific functions, yet there is a relationship between these two concepts. Learn about acids and bases to prepare for the Praxis Middle School Science exam. By the end of this chapter, you should have a stronger comprehension of these topics:

  • Equilibrium between acids and bases
  • Buffer solutions
  • Reactions
  • Autoionization and the dissociation constant
  • Coordination chemistry

Navigating through our materials on Study.com will prove to be an intuitive and user-friendly experience. You can click from one video lesson to the next, or you can scroll ahead to focus on any lesson of your choice. The lesson transcripts are located below the video lessons, so you can read through the transcript for each lesson, or you can scan through the transcripts as a lesson preview.

We understand that when you are studying for the Praxis Middle School Science exam that you will most likely experience higher levels of stress, so just in case you struggle with any of the chapter materials, we have made our instructors available via email to answer your questions.

Praxis Middle School Science: Acid-Base Chemistry Objectives

It is the goal of your state to make sure that all middle school educators have acquired plenty of training and experience to teach students at a level that meets academic standards. To achieve such a goal, many states use such tests as the Praxis Middle School Science exam, since these types of exams are designed to measure each individual's full range of knowledge.

On this specific exam, test-takers will have two hours to answer both multiple-choice and constructed-response style questions. Chemistry is included in the subcategory of the physical sciences, and 22% of the multiple-choice questions will be related to this particular subcategory. To help yourself be more likely to succeed on this exam, make full use of the lessons in the chapter as well as the transcripts, quizzes, and chapter exam.

Test your knowledge with a 30-question chapter practice test
Dissociation Constant and Autoionization of Water

1. 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.

Acid & Base Anhydrides: Definition & Examples

2. 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.

Coordination Chemistry: Bonding in Coordinated Compounds

3. Coordination Chemistry: Bonding in Coordinated Compounds

Discover what a coordinated compound is. Understand how bonding occurs in coordinated compounds and some of the possible shapes coordinated compounds can be. Learn the uses in nature and industry for coordinated compounds.

Precipitation Reactions: Predicting Precipitates and Net Ionic Equations

4. Precipitation Reactions: Predicting Precipitates and Net Ionic Equations

Learn what a precipitate is and predict when it will form in an aqueous chemical reaction, usually a double-replacement reaction. Learn what an ionic equation is, how it differs from a net ionic equation and how to write a net ionic equation.

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

5. 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

6. 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.
