About This Chapter
Shipwrecks, Corrosion & Conservation - Chapter Summary
The lessons in this chapter provide an overview of shipwrecks, corrosion, and conservation. You can review theories of Galvani, Volta, Davy, and Faraday concerning electron transfer reactions. You can also gain an understanding of ocean water gases, how objects in shipwrecks are recovered, and the restoration process of artifacts from shipwrecks. After completing the chapter, you should be prepared to:
- List the physical properties of ocean water
- Explain how electrolytic cells work
- Compare the properties of iron and steel in ships
- Recall facts about electrolysis
- Define corrosion and cathodic protection
- Distinguish between corrosion of active and passivating metals
- Discuss the rate of decay and corrosion in shipwrecks
- Compare the rate of corrosion in acidic and neutral environments
You can study all the lessons in order, or just the topics you need to review. These lessons can help you comprehend relevant details about shipwrecks, and our instructors provide plenty of helpful illustrations. A brief quiz is available for each lesson to test your knowledge, and you can print the quizzes for use as an offline study tool.
1. Properties of Ocean Water
Ocean waters are salty and contain minerals and dissolved gases. They also have a high heat capacity and vary in density depending on temperature and salinity. Learn more about the unique chemical and physical properties of ocean water.
2. Electrolytic Cells
You probably use electrolytic cells every day without ever thinking about it! In this lesson, learn all about electrolytic cells, how they work, and how they compare to voltaic cells.
3. What is Electrolysis? - Definition, Process & Facts
Did you know electrolysis is able to facilitate the decomposition of substances? In this lesson, you'll learn more about the process of electrolysis, after which, you can test your own expertise on the subject with a short quiz.
4. Corrosion: Definition, Prevention & Protection
You've seen metals corrode even if you weren't aware of what was happening. This lesson defines corrosion and examines ways to protect metals, thus preventing corrosion.
5. Rate of Decay & Corrosion in Shipwrecks: Factors & Examples
When ships sink in the ocean they decay. In this lesson, we will investigate why they decay and how fast it happens based on the conditions where the wreck is located.
6. Methods of Corrosion of Shipwrecks: Electrochemical Reactions & Bacteria
In the ocean, shipwrecks undergo corrosion through two methods: redox reactions and bacteria. In this lesson, we will learn how these methods corrode ships.
