This note pack is a comprehensive summary of the core Grade 12 Physical Science topics, designed for revision before exams. Each section provides definitions, key concepts, equations, worked examples, and diagrams where necessary. Electrochemistry • Redox Reactions: Oxidation = loss of electrons, Reduction = gain of electrons. • Electrolytic Cells: Non-spontaneous, require external energy (electroplating, electrolysis). • Galvanic/Voltaic Cells: Spontaneous, produce electricity (Zn...
