The Cambridge O-Level Chemistry (5070) syllabus develops an understanding of chemical principles, reactions, and laboratory skills. It strengthens analytical thinking, numerical application, and experimental competence.

Students typically sit three components:

Paper 1 – Multiple Choice

This paper tests core knowledge, definitions, and quick application of chemical concepts.

Paper 2 – Theory (Structured Questions)

This paper assesses deeper understanding, calculations, and explanation skills.

Experimental Techniques

• Laboratory apparatus and safety.

• Filtration, distillation, chromatography.

• Accuracy, precision, and sources of error.

Particulate Nature of Matter

• States of matter.

• Diffusion and kinetic theory.

Atomic Structure and Bonding

• Structure of the atom.

• Ions and isotopes.

• Ionic and covalent bonding.

• Metallic bonding.

Stoichiometry

• Relative atomic mass and molecular mass.

• Balancing chemical equations.

• Mole concept and calculations.

Acids, Bases and Salts

• pH scale.

• Preparation of salts.

• Neutralisation reactions.

The Periodic Table

• Trends across periods and down groups.

• Properties of Group I, VII, and noble gases.

Metals and Reactivity

• Reactivity series.

• Extraction of metals.

• Corrosion and prevention.

Organic Chemistry

• Hydrocarbons (alkanes and alkenes).

• Functional groups.

• Polymerisation.

Paper 3 – Practical (or Alternative to Practical)

This paper evaluates laboratory and analytical skills.

Practical Skills

• Identifying unknown substances.

• Gas tests and qualitative analysis.

• Titration calculations.

• Recording observations accurately.

• Drawing and interpreting graphs.

Key Notes

• Balanced equations and correct units are essential.

• Strong understanding of the mole concept is crucial.

• Clear explanations improve theory marks.

• Practical knowledge supports theoretical understanding.
