- Define autoionization of water
- Discuss titration of a strong acid
As you go through these lessons on acids and bases in chemistry, you can send a message to instructors if you get stuck on a topic. You can review all of the lessons in order, or just the topics that you need to review. Quizzes are available for each lesson to gauge your knowledge of the topics covered.
1. Bronsted-Lowry Acid: Definition & Examples
Two scientists came to a conclusion: an acidic solution behaves as proton donors, which is in the form of a hydrogen ion. This is what we call the Bronsted-Lowry definition of an acid, which is the main focus of this lesson.
2. Bronsted-Lowry Base: Definition & Examples
There are different definitions of bases from different scientists, so what classifies a solution as basic? In this lesson, we will learn about the definition of a basic solution proposed by two scientists, Bronsted and Lowry.
3. Writing BronstedLowry Equations
In this lesson you will learn about Bronsted-Lowry acids and bases, as well as how to write them in an equation. You will also learn how to balance charges and atoms, ensuring a correctly written equation.
4. 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.
5. 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.
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.
7. Amphiprotic Substances: Definition & Examples
In acid-base chemistry, did you know water is a very common amphiprotic substance? Explore this lesson to learn what amphiprotic is and identify different compounds classified as amphiprotic.
8. 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.
9. 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.
10. 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.
