Chemistry study guides

A deep-dive Edexcel GCSE Chemistry guide to Topic 1 Key concepts in chemistry. Covers atomic structure and isotopes, the periodic table and electronic configuration, ionic, covalent and metallic bonding and the structures they form, chemical formulae and equations, and the core calculations including empirical formulae, reacting masses, concentration and the mole.

A deep-dive Edexcel GCSE Chemistry guide to Topic 2 States of matter and mixtures. Covers the particle model and changes of state, pure substances and mixtures, filtration, crystallisation and distillation, paper chromatography and Rf values, and producing potable water.

A deep-dive Edexcel GCSE Chemistry guide to Topic 3 Chemical changes. Covers acids, bases and the pH scale, strong and weak acids, the reactions of acids with metals, oxides, hydroxides and carbonates, preparing soluble and insoluble salts, and the electrolysis of molten compounds and solutions.

A deep-dive Edexcel GCSE Chemistry guide to Topic 4 Extracting metals and equilibria. Covers the reactivity series, oxidation and reduction, the reactions of metals with oxygen, water and acids, displacement, extracting metals by carbon and by electrolysis, biological extraction, recycling, and reversible reactions and dynamic equilibrium.

A deep-dive Edexcel GCSE Chemistry guide to Topic 5 Separate chemistry 1. Covers the transition metals, alloys and corrosion, and the quantitative analysis content: moles and concentration, the titration core practical and calculations, percentage yield, atom economy, and gas volumes using the molar gas volume.

A deep-dive Edexcel GCSE Chemistry guide to Topic 6 Groups in the periodic table. Covers the Group 1 alkali metals and their increasing reactivity, the Group 7 halogens and their decreasing reactivity and displacement reactions, the Group 0 noble gases and their inertness, and how each trend is explained by electronic structure.

A deep-dive Edexcel GCSE Chemistry guide to Topic 7 Rates of reaction and energy changes. Covers collision theory and the factors affecting rate, measuring rate by gas volume and colour change, calculating rate from graphs, catalysts, exothermic and endothermic reactions and reaction profiles, and bond energy calculations.

A deep-dive Edexcel GCSE Chemistry guide to Topic 8 Fuels and Earth science. Covers crude oil and the alkanes, fractional distillation and the property trends, complete combustion and cracking, the pollutants from burning fuels and acid rain, hydrogen as a fuel, the evolution of the atmosphere and the greenhouse effect and climate change.

A deep-dive Edexcel GCSE Chemistry guide to Topic 9 Separate chemistry 2. Covers qualitative analysis (flame tests and tests for cations and anions), the alcohols and carboxylic acids and their reactions, and polymers and materials including addition and condensation polymerisation and life cycle assessment.
