GCSE Chemistry — Extracting Metals and Equilibria

Led by Humphry Davy

1 modules ~5 hours of tutorial Chemistry Updated today

Module 7 of Edexcel GCSE Chemistry. Led by Sir Humphry Davy, who isolated potassium, sodium, calcium, magnesium, strontium, and barium for the first time in history. The student covers the reactivity series, metal extraction by carbon-reduction and electrolysis, biological alternatives, recycling and life-cycle assessment, reversible reactions, and the Haber process for ammonia.

    Extracting Metals and Equilibria

    Led by Humphry Davy

    The question

    How does a chemist deduce the relative reactivity of metals from a small set of experiments, what method should be used to extract any given metal from its ore, and how does the principle of reversible reactions and dynamic equilibrium govern industrial processes like the Haber synthesis of ammonia? The spec asks the student to construct the reactivity series, explain displacement as redox (Higher), choose extraction methods by reactivity-series position, evaluate biological alternatives and recycling, define reversible reactions and dynamic equilibrium, recall the Haber process and its industrial conditions, and predict equilibrium response (Higher).

    Outcome

    the student can deduce metal reactivity from observed reactions, explain displacement as redox, choose the correct extraction method for any metal, evaluate biological alternatives and recycling, explain reversible reactions and dynamic equilibrium, recall the Haber process conditions, and predict equilibrium response to changes (Higher). *(Edexcel 1CH0 Paper 1 — Topic 4, spec points 4.1–4.17)*
