Separation Techniques
Learn how to identify mixtures and choose the correct method to separate them. This module covers all separation techniques tested in ZIMSEC exams, with a strong focus on the science behind each method — not just the procedure.
- 1.1Mixtures vs. Pure SubstancesIncluded
- 1.2Filtration and EvaporationIncluded
- 1.3Distillation and Fractional DistillationIncluded
- 1.4ChromatographyIncluded
- 1.5Choosing the Right Technique — Exam PracticeIncluded
Particulate Nature of Matter
Build a solid understanding of the kinetic particle theory, states of matter, atomic structure, and bonding. This module forms the foundation for everything else in O Level Chemistry.
- 2.1Kinetic Particle Theory and States of MatterIncluded
- 2.2Diffusion and Evidence for ParticlesIncluded
- 2.3Atomic StructureIncluded
- 2.4Chemical BondingIncluded
Acids, Bases, and Salts
Master the chemistry of acids and bases, pH, neutralisation reactions, and the preparation of salts by three different methods. This is one of the highest-weighted sections in the ZIMSEC O Level exam.
- 3.1Properties of Acids and BasesIncluded
- 3.2pH Scale and IndicatorsIncluded
- 3.3Neutralisation and Salt FormationIncluded
- 3.4Preparation of SaltsIncluded
- 3.5Qualitative Analysis of SaltsIncluded
Industrial Processes
Understand the large-scale chemistry that underpins modern industry — the Haber Process, the Contact Process, metal extraction, and the electrolysis of brine. Learn to evaluate conditions in terms of rate, yield, and cost.
- 4.1The Haber ProcessIncluded
- 4.2The Contact ProcessIncluded
- 4.3Extraction of MetalsIncluded
- 4.4Electrolysis of Brine and Industrial ElectrolysisIncluded
Oxidation and Reduction
Develop a complete and exam-ready understanding of redox chemistry using three definitions — oxygen transfer, hydrogen transfer, and electron transfer. Identify oxidising and reducing agents and apply redox concepts to real reactions.
- 5.1Defining Oxidation and ReductionIncluded
- 5.2Oxidation StatesIncluded
- 5.3Oxidising and Reducing AgentsIncluded
- 5.4Redox in Everyday and Industrial ContextsIncluded
- 5.5Module 5 Review and Exam SprintIncluded
