GCSE Chemistry - What is Corrosion and How to Stop it #71

The video tutorial explores the concept of corrosion, focusing on rusting, a type of corrosion where iron reacts with oxygen and water to form rust. It explains the redox reaction involved in rusting and the conditions necessary for it to occur. The tutorial also compares how different metals like iron and aluminum corrode, highlighting the protective layer formed by aluminum oxide. Finally, it discusses methods to prevent rusting, including barrier methods like painting and electroplating, and sacrificial methods such as galvanizing with zinc.
