About this course
The eighth and closing module of Paper 1 of the Edexcel GCSE Chemistry course bundles together the transition metals, the working chemist's quantitative-analysis toolkit, and the industrial chemistry of the Haber process and fuel cells. The student leaves the module fluent in the calculations a real chemist runs daily — concentrations, titrations, percentage yields, atom economies, molar volumes — and able to evaluate industrial chemistry against green-chemistry criteria.
It is led by Michael Faraday, who began as a bookbinder's apprentice and became, by his mid-thirties, the most important experimentalist of the nineteenth century. His laws of electrolysis are the quantitative foundation of every electrochemical process in this module.
The student leaves the module able to describe transition-metal properties, explain rust prevention and electroplating, account for alloys, carry out 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.

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)*
