Revise GCSE Chemistry with free one-page cheat sheets. Each poster brings the key ideas from one topic together on a single page, so you can see how everything connects and spot anything you still need to learn.
The three states of matter, particle arrangements and forces, changing state, energy changes during melting and boiling, and state symbols in equations.
pH scale, acid-alkali neutralisation, strong vs weak acids, acid reactions and salt naming, and the titration method with concordant titres.
Splitting ionic compounds using electricity - what electrolysis is, the molten aluminium oxide example, and rules for aqueous solutions.
Exothermic vs endothermic reactions, reaction profiles with activation energy, and bond energy calculations including worked examples.
What rate of reaction means, how to measure and calculate it, collision theory, the four factors that affect rate, and how catalysts work.
Naming rules, alkane and alkene structures, alcohols, carboxylic acids and esters - functional groups, reactions, general formulae and the first four members of each family.
Hydrocarbons and alkanes, fractional distillation column, cracking long-chain alkanes, complete and incomplete combustion, and atmospheric pollutants.
Addition and condensation polymerisation, polyesters and polypeptides with worked equations, examples of common polymers, and disposal issues.
Gas tests, flame tests, cation tests with NaOH, and anion tests for halides, sulfates, nitrates and carbonates.
Filtration, crystallisation, simple and fractional distillation, and paper chromatography - methods, apparatus, and when to use each technique.
