L8 Titanium Extraction The Kroll Process (Unit 5 Chemistry BTEC Applied Science)

Pearson BTEC Applied Science Unit 5 Chemistry A1 Bundle

This eight-lesson PowerPoint bundle covers Pearson BTEC Applied Science Unit 5 Chemistry A1: Relating Properties to Uses and Production of Substances. It provides a complete teaching sequence linking chemical properties to industrial uses, electrolysis, transition metals, catalysis, and the extraction and processing of important metals. The bundle begins with metal oxides, hydroxides and alumina, including their basic behaviour, amphoteric aluminium oxide, the use of calcium hydroxide to treat acidic effluent, and the use of alumina as a refractory material. Students are then introduced to electrolysis, covering electrolytes, electrodes, ion movement, oxidation, reduction and half-equations. This knowledge is applied to the electrolysis of brine, including the production of chlorine, hydrogen and sodium hydroxide and the use of diaphragm and membrane cells to separate the products. The transition-metal section develops understanding of variable oxidation states, coloured compounds, complex ions, ligands and dative covalent bonding. A dedicated lesson on transition metals as catalysts then covers activation energy, homogeneous and heterogeneous catalysis, adsorption, catalyst poisoning, the Contact process and the Haber process. The final three lessons focus on industrial production. Students study the Bayer process for converting bauxite into alumina, the Hall–Héroult process for extracting aluminium by electrolysis, and the Kroll process for extracting titanium via titanium(IV) chloride. All eight resources are supplied as fully editable PowerPoint (.pptx) files and include learning objectives, key terminology, starter activities, structured explanations, worked examples, student tasks, answer slides and check-your-understanding questions. Updated in 2026, this bundle is suitable for classroom teaching, revision, cover lessons or independent study for Pearson BTEC Applied Science Unit 5 Chemistry A1.
