AQA GCSE Chemistry
Chemistry Revision
Video guides, podcast episodes, topic breakdowns, study tips and exam technique — everything you need to tackle AQA GCSE Chemistry with confidence.
Chemistry underpins the material world — from atomic structure to rates of reaction. These resources follow the AQA specification closely and are designed to build your understanding topic by topic, with clear explanations and exam-focused guidance.
AQA GCSE Chemistry topics
Atomic Structure & the Periodic Table
Atoms, elements, compounds, the development of the periodic table and trends.
Bonding, Structure & Properties
Ionic, covalent and metallic bonding — and how structure determines properties.
Quantitative Chemistry
Moles, relative formula mass, concentration and yield calculations.
Chemical Changes
Reactivity series, electrolysis, acids and bases, and pH.
Energy Changes
Exothermic and endothermic reactions, bond energies and reaction profiles.
Rates of Reaction & Equilibrium
Factors affecting rate, collision theory and Le Chatelier's principle.
Organic Chemistry
Alkanes, alkenes, polymers and the basics of crude oil.
Chemical Analysis & the Atmosphere
Purity, chromatography, the history of the atmosphere and climate change.

Study tips for AQA Chemistry
Learn your formulae and equations — many marks are lost by writing them incorrectly.
Practise mole calculations regularly; they appear across multiple topics.
Understand the required practicals — especially titration, electrolysis and chromatography.
Use colour-coded notes to separate the three main bonding types and their properties.
Exam technique
Chemistry exams reward precision and method. These habits will help you pick up every available mark.
Always include units in calculation answers — a number without a unit is an incomplete answer.
For 'explain' questions about bonding or reactions, link structure to property explicitly.
Show all working in multi-step calculations — method marks are available even if the final answer is wrong.
Read graph and data questions carefully — the examiner is testing your ability to interpret evidence, not just recall facts.
