About This Chapter
Chemical Analysis - Chapter Summary
This chapter includes lessons on chemical analysis. There are informative discussions covering use of sodium hydroxide, identification of metal ions, and identifying common gases. You will review the definition of pure substances, learn their properties and see examples. Another lesson helps you identify carbonates, halides and sulfates. After completing the chapter, you should be able to do the following:
- Define pure substance in chemistry
- Discuss uses of formulations in chemistry
- Explore tests to identify common gases
- Describe use of flame tests to identify metal ions
- Examine how to use a sodium hydroxide solution to identify metal ions
- Identify carbonates, halides, and sulfates
- Explain instrumental methods for identifying elements and compounds
We use short text and video lessons, which help you easily understand the information presented. Our expert instructors employ an engaging teaching style and use plenty of examples. The video timelines let you navigate the video lessons and jump straight to the topics that are of greatest interest to you. Each lesson includes a short multiple-choice quiz to test your knowledge.
1. Pure Substance in Chemistry: Definition, Properties & Examples
This lesson introduces the concept of the pure substance. The impact of purity on the physical and chemical properties are discussed and several examples are explored along the way.
2. Formulations in Chemistry: Definition, Creation & Uses
In this lesson we will describe the very broad field of formulation chemistry and look at few examples of different formulations found in every day life.
3. Tests for Identifying Common Gases
Have a mystery gas you need to identify? You have come to the right place. This lesson discusses the tests needed to identify hydrogen, oxygen, carbon dioxide, and chlorine gas.
4. Using Flame Tests to Identify Metal Ions
In this lesson, we'll be learning how to use the flame test to identify different metal ions. By the end, you'll be able to explain how to do the test and predict which metals will produce which color flames.
5. Using Sodium Hydroxide Solution to Identify Metal Ions
Sodium hydroxide is a base, and reacts with metallic ions. The results of these reactions can be used to identify the metal in the ionic compound. In this lesson, we will learn how to conduct these tests and how to interpret the results.
6. Identifying Carbonates, Halides & Sulfates
Watching what happens in chemical reactions can help identify unknown compounds. In this lesson, we will learn how to identify carbonates, halides, and sulfates.
7. Instrumental Methods for Identifying Elements & Compounds
In this lesson, we will discuss some common techniques scientist use to identify atoms and molecules. Specifically, we will introduce the field of spectroscopy.
