IGCSE Chemistry Revision - 24 - Extraction of Aluminium

This video goes into detail about the preparation and electrolysis for the extraction of aluminium from the initial natural resource bauxite. In addition, I also discuss the economic and environmental issues that relate to this process and hence show the importance of recycling aluminium. Timestamps: 0:00 Introduction 1:32 Bauxite (raw ingredient) 2:30 Why electrolysis? - Reactivity Series 3:06 Electrolysis Methods 3:24 Step 1 - Sodium Hydroxide Treatment 4:05 Step 2 - Precipitation 5:02 Step 3 - Formation 5:45 Step 4 - Electrolysis 9:15 Step 4 - Economic Considerations 11:16 Key Equations I hope you enjoy this video and goodluck on your revision!
