Chapter Explainers
Online one-to-one SPM Chemistry, taught by an experienced teacher.
Manufactured Substances in Industry: What to Remember
Alloys, composites, glass and ceramics, the facts, compositions and uses from this SPM Chemistry chapter that you actually need to memorise, organised clearly.
2026-09-04Chapter ExplainersPolymers and Everyday Materials in SPM Chemistry
How monomers build polymers, addition versus condensation, natural rubber and vulcanisation, and the everyday materials this chapter explains.
2026-09-04Chapter ExplainersRate of Reaction: The Concepts Behind the Graphs
Why rate-of-reaction curves rise, curve and flatten, the collision-theory ideas that make every SPM rate graph make sense, not just the reading of them.
2026-09-04Chapter ExplainersRedox Reactions Explained Simply for SPM
Redox made plain: electron transfer, OIL RIG, oxidation numbers and how to spot the oxidising and reducing agent in any SPM Chemistry reaction.
2026-09-04Chapter ExplainersThe Definitions You Must Know for SPM Chemistry
The exact SPM Chemistry definitions examiners want, word for word, mole, rate, exothermic, oxidation, acid and more, with why the precise wording earns the mark.
2026-09-04Chapter ExplainersThe Formulae You Must Know for SPM Chemistry
A compact, exam-ready list of every formula SPM Chemistry expects, moles, concentration, dilution, rate and heat, with the constants and what each symbol means.
2026-09-04Chapter ExplainersThe Ion Colours and Tests You Must Know for SPM
SPM qualitative analysis, organised, ion colours in solution, precipitate colours with NaOH and ammonia, flame tests, and the confirmatory tests for common ions.
2026-09-04Chapter ExplainersThe Periodic Table: Trends You Must Know
Atomic radius, electronegativity, and the reactivity of Groups 1, 17 and 18, the periodic trends SPM Chemistry keeps testing, explained by nuclear charge and shells.
2026-09-04Chapter ExplainersThe Trickiest Topics in Form 4 SPM Chemistry
The Form 4 topics that trip students up most, why each one is hard, and a clear way through: the mole, bonding, electron arrangement, molarity and rate graphs.
2026-09-04Chapter ExplainersThe Trickiest Topics in Form 5 SPM Chemistry
The Form 5 topics students find hardest, why each one is tough, and how to master them: thermochemistry, redox, electrolysis, organic naming and polymers.
2026-09-04Chapter ExplainersThermochemistry: Understanding Energy Changes
Exothermic vs endothermic, energy level diagrams, bond energy and the heat-of-reaction calculation, the whole SPM thermochemistry chapter made intuitive.
2026-09-04Chapter ExplainersUnderstanding Electron Arrangement and the Periodic Table
Electron arrangement is the hidden key to the Periodic Table. Learn how shells, groups and periods connect so the table stops being something to memorise.
