GCSE Chemistry — Quantitative and Transition Chemistry

Led by Michael Faraday

Module 8 of Edexcel GCSE Chemistry — the closing module of Paper 1. Led by Michael Faraday, whose laws of electrolysis gave electrochemistry its quantitative foundation. The student covers transition metals and corrosion, electroplating and alloys, the full quantitative-analysis toolkit (titration, percentage yield, atom economy, molar volume), the Haber process in industrial detail, fertilisers, and hydrogen-oxygen fuel cells.

1. Module 8

   Quantitative and Transition Chemistry

   Led by Michael Faraday

   The question

   What is distinctive about the transition metals, how does a chemist quantitatively analyse a reaction (titration, yield, atom economy, molar volume), and how do industrial processes like the Haber synthesis and hydrogen-oxygen fuel cells balance chemistry against economics? The spec asks the student to describe transition-metal properties; explain corrosion, rust prevention, and electroplating; account for alloy strength; perform titration and yield calculations; apply molar volume and Avogadro's law; recall the Haber industrial conditions; and evaluate fertilisers and fuel cells.

   Outcome

   the student can describe transition-metal properties, explain rust prevention by all three methods, describe electroplating, account for alloy strength, calculate concentrations and analyse titrations (Core Practical 5.9C), calculate percentage yield and atom economy, apply molar volume to gas calculations, account for industrial Haber conditions, and evaluate fuel-cell technology. *(Edexcel 1CH0 Paper 1 — Topic 5, spec points 5.1C–5.27C — all Higher tier, Separate-Chemistry only)*
