About This Chapter
1. Acidic Solutions: Properties & Examples
Acidic solutions are found everywhere in the natural world and are an important part of our everyday lives. This lesson defines acidic solutions and discusses their fundamental properties. Several examples of acidic solutions from the natural world and industry are also provided.
2. Arrhenius Acid: Definition & Examples
A scientist named Svante Arrhenius defined an acid as a compound that increases the proton (H+) concentration in a solution. This definition of an acid is what we now call an Arrhenius acid, which is the main focus of this lesson.
3. Buffer System in Chemistry: Definition & Overview
In many ways, our lives are dependent on functioning buffer systems. Learn the definition of a buffer system, understand how it works and assess your knowledge with a quiz.
4. Chemical Reaction Catalyst: Rates & Overview
Catalysts are common in both industrial processes and in the human body. This lesson will explain how they work and why we need them. A quiz will test our knowledge.
5. Closed System in Chemistry: Definition & Example
This lesson provides a basic definition of a closed system from thermodynamics. Examples are included to provide students with illustrations of closed systems that are encountered within chemistry.
6. Combination Reaction: Definition & Examples
There many types of chemical reactions. In a combination reaction, you can predict the product if you know what goes into it. Find out more about combination reactions and see some examples.
7. What is Sodium Bicarbonate? - Structure, Formula & Uses
Have you experienced heartburn? Do you like cooking and baking? Have you encountered stubborn stains? If you answered yes to any of these, then sodium bicarbonate is your friend. In this lesson, we will discuss sodium bicarbonate and its many uses.
8. What Does Chemical Mean in Science?
In this lesson we will learn what a chemical is, how it is defined in science, and the importance of chemicals to our life. We will also learn how society views chemicals versus the definition in science.
9. Aqueous Solution: Definition, Reaction & Example
Rainwater, Gatorade, and orange juice. These are just a few great examples of aqueous solutions. Read on to learn about aqueous solutions and their reactions in the environment.
10. Concentration Gradient: Definition & Example
In this lesson, you'll learn about the concentration gradient and its processes, as well as about the two types of diffusion, passive and facilitative, that happen along the concentration gradient.
11. Conjugate Base: Definition & Overview
In this lesson, you'll learn about conjugate bases in chemistry and where they come from. You'll also learn about their relationship to acids and see how acid-base reactions work.
12. Denaturation of Protein: Definition & Causes
Proteins are found in all living organisms. Problems occur when proteins become denatured. In this lesson, you will learn about a change in proteins known as denaturation.
13. Endothermic Reaction: Definition & Example
Chemical reactions usually involve the exchange of energy in some form. In this lesson, you will learn about a type of reaction known as an endothermic reaction.
14. Weak Bases: Examples & Overview
Did you know household ammonia, which is used as a cleaning product, can be classified as a weak base? Continue reading to learn about weak bases and discover more examples of these type of chemical substances.
15. What is Nitric Acid? - Structure, Uses & Formula
In addition to its uses in chemical laboratories, nitric acid is utilized in fertilizer, rocket fuel, and metallurgy. In this lesson, we will discuss nitric acid and its different uses, as well as learn about its formula and structure.
16. Amphoteric: Definition, Properties & Examples
There are substances that can only act as an acid and those that can only act as a base. However, there are also substances that can do both - these are called amphoteric substances. In this lesson, we will learn all about the amphoteric substances.
17. 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.
18. Exothermic Reaction: Definition & Example
Many chemical reactions occur everyday and can have very different results. In this lesson, you will learn about chemical reactions that are considered to be exothermic.
19. Lewis Acid: Definition, Theory & Examples
This lesson will introduce a new way of looking at acid and base chemistry. We will learn how to identify Lewis acids and how they react with Lewis bases. A quiz will test what we have learned.
20. Lewis Base: Definition & Examples
Every day, we encounter solutions that can be classified as bases. What exactly is a base? A scientist named Gilbert N. Lewis came up with a definition of a basic solution, referred to as a Lewis base, which we will discuss in this lesson.
21. Oxidizing Agent: Definition & Examples
There are many common processes, such as rusting, aging and combustion, that involve substances called oxidizing agents. In this lesson, we will discuss the definition and common examples of oxidizing agents.
22. What is Acid in Chemistry? - Definition & Overview
Acids are chemical agents that release hydrogen ions when added to water. Their chemistry makes them one of the most important classes of molecules in nature and science. This article addresses acids and their properties.
23. What is Oxidation? - Definition, Process & Examples
In this lesson, learn about oxidation and its process, and examine some examples of oxidation, including the mystery of browning fruit. Then, measure what you've learned with a quiz.
