Corrosion

Welcome to our lesson on corrosion! In this video, we dive into the essentials of corrosion and reveal how to understand and manage this common chemical phenomenon. You'll learn how to explain what corrosion is and why it mostly affects metals when they are exposed to oxygen.
📚 In this lesson, you will learn:
How to define corrosion and understand the prerequisites for it, including the presence of oxygen.
How to recognise oxidation and reduction processes. Learn that oxidation involves a loss of electrons, while reduction involves a gain, often occurring together in redox reactions.
How to explain the process of metal oxidation in redox reactions resulting in metal oxides such as rust from iron.
How to identify the implications of corrosion on the structural integrity of metals like iron and its alloys in everyday applications.
✨ Key concepts covered:
Understanding corrosion: Gain a clear insight into why transition metals like iron corrode when exposed to an oxygen-rich environment.
Redox reactions: Master the paired chemical processes of oxidation and reduction that underpin corrosion.
Rust formation: Discover how and why rust forms, specifically on iron and steel, and how it exemplifies the corrosion process.
Practical implications: Learn why understanding corrosion mechanisms is crucial in fields like construction and engineering, and how it informs the use of protective measures.
