Every section of Cambridge IGCSE Chemistry 0620, one-to-one with the official document. Visual lessons, interactive labs, and exam-style practice will be added topic by topic. Published topics open; the rest are planned.
Trainers for the practical papers, marked the way examiners mark. See every practical trainer.
Solids, liquids and gases as particles in motion. The kinetic particle model, changes of state, and diffusion: the ideas every later topic leans on.
What matter is made of and how it holds together. Atomic structure, isotopes, and the three kinds of bonding that explain almost every property in the course.
Formulae, equations and the mole. The counting that turns a chemical equation into masses, volumes and concentrations you can measure.
Using electricity to drive reactions that will not happen on their own. Electrolysis of melts and solutions, electroplating, and the hydrogen fuel cell.
Where the heat comes from. Exothermic and endothermic reactions, reaction pathway diagrams, activation energy, and bond energies.
How fast, how far, and who loses electrons. Rates of reaction, reversible reactions and equilibrium, and redox.
The chemistry of the school lab bench. Properties of acids and bases, the pH scale, oxides, and the three ways to prepare a salt.
One table, every element, and the patterns that let you predict a reaction you have never seen. Groups I and VII, the transition elements and the noble gases.
From the reactivity series to the blast furnace. Properties, alloys, corrosion, and how metals are won from their ores.
Water, fertilisers, air and climate. The applied topic that connects the syllabus to the world outside the lab.
The chemistry of carbon. Naming and drawing organic compounds, fuels, and the alkanes, alkenes, alcohols, carboxylic acids and polymers.
The practical half of the course. Experimental design, titrations, chromatography, separation and purification, and the tests for ions and gases.
The full 9701 syllabus, mapped the same way.
